* eeepc-laptop: re-add check for eeepc->backlight == NULLAlan Jenkins2009-12-091-17/+25
| | | | | | | | | | | | | As Corentin points out, we do not create a backlight device if the ACPI video driver is able to provide equivalent functionality. So we do need to check before we try to update the backlight device. We now ignore brightness events completely if we have not created a backlight device. This is slightly more cautious than the original check. Signed-off-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk> Signed-off-by: Len Brown <len.brown@intel.com>

* asus-laptop: add Lenovo SL hotkey supportIke Panhc2009-12-091-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Lenovo SL series laptop has a very similar DSDT with Asus laptops. We can easily have the extra ACPI function support with little modification in asus-laptop.c Here is the hotkey enablement for Lenovo SL series laptop. This patch will enable the following hotkey: - Volumn Up - Volumn Down - Mute - Screen Lock (Fn+F2) - Battery Status (Fn+F3) - WLAN switch (Fn+F5) - Video output switch (Fn+F7) - Touchpad switch (Fn+F8) - Screen Magnifier (Fn+Space) The following function of Lenovo SL laptop is still need to be enabled: - Hotkey: KEY_SUSPEND (Fn+F4), KEY_SLEEP (Fn+F12), Dock Eject (Fn+F9) - Rfkill for bluetooth and wlan - LenovoCare LED - Hwmon for fan speed - Fingerprint scanner - Active Protection System Signed-off-by: Ike Panhc <ike.pan@canonical.com> Signed-off-by: Len Brown <len.brown@intel.com>

* eeepc-laptop: callbacks should use "driver data" parameter or fieldAlan Jenkins2009-12-091-198/+268
| | | | | | | | | | | | | | | | | | | | | | | | | | Callback methods should not refer to a variable like "eeepc" (formally "ehotk"). Instead, they should extract the data they need either from a "driver data" parameter, or the "driver data" field of the object which they operate on. The "eeepc" variable can then be removed. In practice, drivers under "drivers/platform" can get away without using driver data, because it doesn't make sense to have more than one instance of them. However this makes it harder to review them for correctness. This is especially true for core ACPI developers who have not previously been exposed to this anti-pattern :-). This will serve as an example of best practice for new driver writers (whether they find it themselves, or have it pointed out during review :-). The hwmon sub-device is a special case. It uses ec_{read,write} which are defined to communicate with the (first) EC, so it does not require any driver data. It should still only be instantiated in the context of an ASUS010 device because we don't have a safe way to probe for it.

* eeepc-laptop: revise namesAlan Jenkins2009-12-091-128/+125
| | | | | | | | | | | | | | | | | | | | | | | | | | eeepc-laptop now does a lot more than just hotkeys. Replace the "hotk" names used throughout the driver with some slightly more appropriate names. The actual strings used in kernel messages and sysfs are left unchanged. e.g. EEEPC_HOTK_FILE -> EEEPC_LAPTOP_FILE EEEPC_HOTK_HID -> EEEPC_ACPI_HID eeepc_hotk_notify -> eeepc_acpi_notify struct eeepc_hotk -> struct eeepc_laptop ehotk -> eeepc I'm about to refactor the entire driver to remove the global "ehotk" variable, and I don't wish to add "struct eeepc_hotk *ehotk" to functions which have nothing to do with hotkeys. Also - fix the name of "eepc_get_entry_by_keycode()" - remove the unused definition of NOTIFY_WLAN_ON.

* eeepc-laptop: code movementAlan Jenkins2009-12-091-472/+462
| | | | | | | | | | | | | | | | Move e.g. backlight_init() and backlight_exit() together along with the other backlight functions, instead of grouping init() and exit() functions. Move e.g. backlight_ops to follow the functions it refers to, and remove the forward declarations. The code itself should remain unchanged. The eeepc-laptop driver implements a number of interfaces like the backlight class driver. This change makes it easier to examine the implementation of one interface at at a time, without having to search through the file to find init() and exit() functions etc. Signed-off-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk> Signed-off-by: Len Brown <len.brown@intel.com>
* eeepc-laptop: move platform device initialisation to a separate functionAlan Jenkins2009-12-091-25/+39
| | | | | | | | | | | This moves the sysfs_create_group() call just after the declaration of the platform device attributes.

* eeepc-laptop: refactor notificationsAlan Jenkins2009-12-091-32/+39
| | | | | | | | | | | | | | Separate out input_notify(), in a similar way to how notify_brn() is already separated. This will allow all the functions which refer to the input device to be grouped together. This includes a small behaviour change - we now synthesize brightness up/down key events even if the brightness is already at the maximum/minimum value. This is consistent with the new uevent interface. Signed-off-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk> Signed-off-by: Len Brown <len.brown@intel.com>
* eeepc-laptop: simplify how the hwmon device reads values from the ECAlan Jenkins2009-12-091-22/+21
| | | | | | | | | | | | | | The hwmon device uses ec_write() to write values to the EC. So for consistency it should use ec_read() to read values. The extra layers of indirection used did not add any value. This may mean we no longer take the ACPI global lock for such reads (if the EC operation region requires the lock and the EC does not). But there is no point locking each one-byte read individually, when write operations do not use the lock at all.

* eeepc-laptop: fix value of pwm1_enable to match documentationAlan Jenkins2009-12-091-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Documentation/hwmon/sysfs-interface tells us that automatic fan speed control should be represented by a value of 2 or above for pwm1_enable. Fix eeepc_get_fan_ctrl() to return 2 for automatic fan control. Setting "1" for manual control is already consistent with the documentation, so this remains unchanged. Let's preserve the ABI for this specific driver, so that writing "0" will still invoke automatic control. (The documentation says setting "0" should leave the fan at full speed all the time. This mode is not directly supported by our hardware. Full speed is rather noisy on my 701 and the automatic control has never used it. If you really want this e.g. to prolong the life of an EeePC used as a server, you can always use manual mode. hwmon has always been fairly machine-specific, and you're in a tiny minority (or elite :-). I'm sure you're smart enough to notice that the fan doesn't turn on to full speed when you try this mode, either by ear or checking fan_input1. We could even claim to be honouring the spirit of the documentation. "0" really means "safe mode". EeePCs default to automatic mode, ie that is what Asus will actually test. Since we do not provide any way to tamper with the temperature threshold, automatic mode _is_ the safe option).

But in fact it is not needed in mainline because the earlier commit dd00a99e7a fixes the same problem in a better way. Further, this commit introduces a bug in the way it interacts with the automatic read-error-correction. If, after a read error is successfully corrected, the same disk is chosen to re-read - the re-read won't be attempted but an error will be returned instead. After reverting that commit, there is the possibility that a read error on a read-only array (where read errors cannot be corrected as that requires a write) will repeatedly read the same device and continue to get an error. So in the "Array is readonly" case, fail the drive immediately on a read error. Signed-off-by: NeilBrown <neilb@suse.de> Cc: stable@kernel.org

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the parisc architecture we face for each and every loaded kernel module this kernel "badness warning": sysfs: cannot create duplicate filename '/module/ac97_bus/sections/.text' Badness at fs/sysfs/dir.c:487 Reason for that is, that on parisc all kernel modules do have multiple .text sections due to the usage of the -ffunction-sections compiler flag which is needed to reach all jump targets on this platform. An objdump on such a kernel module gives: Sections: Idx Name Size VMA LMA File off Algn 0 .note.gnu.build-id 00000024 00000000 00000000 00000034 2**2 CONTENTS, ALLOC, LOAD, READONLY, DATA 1 .text 00000000 00000000 00000000 00000058 2**0 CONTENTS, ALLOC, LOAD, READONLY, CODE 2 .text.ac97_bus_match 0000001c 00000000 00000000 00000058 2**2 CONTENTS, ALLOC, LOAD, READONLY, CODE 3 .text 00000000 00000000 00000000 000000d4 2**0 CONTENTS, ALLOC, LOAD, READONLY, CODE ... Since the .text sections are empty (size of 0 bytes) and won't be loaded by the kernel module loader anyway, I don't see a reason why such sections need to be listed under /sys/module/<module_name>/sections/<section_name> either. The attached patch does solve this issue by not exporting section names which are empty.
