* driver core: Convert some drivers to CLASS_ATTR_STRINGAndi Kleen2010-03-081-9/+4
| | | | | | | | | | Convert some drivers who export a single string as class attribute to the new class_attr_string functions. This removes redundant code all over. Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* driver-core: Add attribute argument to class_attribute show/storeAndi Kleen2010-03-081-1/+1
| | | | | | | | | | | | | | | | | | | | Passing the attribute to the low level IO functions allows all kinds of cleanups, by sharing low level IO code without requiring an own function for every piece of data. Also drivers can extend the attributes with own data fields and use that in the low level function. This makes the class attributes the same as sysdev_class attributes and plain attributes. This will allow further cleanups in drivers. Full tree sweep converting all users. Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* headers: remove sched.h from interrupt.hAlexey Dobriyan2009-10-111-0/+1
| | | | | | | | After m68k's task_thread_info() doesn't refer to current, it's possible to remove sched.h from interrupt.h and not break m68k! Many thanks to Heiko Carstens for allowing this. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>
* const: constify remaining file_operationsAlexey Dobriyan2009-10-021-1/+1

* trivial: fix an -> a typos in documentation and commentsFrederik Schwarzer2009-01-061-1/+1
| | | | | | | | | | | It is always "an" if there is a vowel _spoken_ (not written). So it is: "an hour" (spoken vowel) but "a uniform" (spoken 'j') Signed-off-by: Frederik Schwarzer <schwarzerf@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
* device create: misc: convert device_create_drvdata to device_createGreg Kroah-Hartman2008-10-161-3/+3
| | | | | | | | Now that device_create() has been audited, rename things back to the original call to be sane. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* drivers/misc/phantom: note PCIJiri Slaby2008-07-251-1/+1
| | | | | | | | | Tell users that the driver is only for PCI devices to stop asking for support of firewire and parallel devices. Signed-off-by: Jiri Slaby <jirislaby@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* device create: misc: convert device_create to device_create_drvdataGreg Kroah-Hartman2008-07-221-2/+3
| | | | | | | | device_create() is race-prone, so use the race-free device_create_drvdata() instead as device_create() is going away. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* phantom: BKL pushdownJonathan Corbet2008-06-201-2/+7
| | | | | | Add explicit lock_kernel calls to phantom_open(). Signed-off-by: Jonathan Corbet <corbet@lwn.net>
* Misc, phantom, fix pollJiri Slaby2008-04-291-4/+6
| | | | | | | | | Return ERR even if there are pending data, but hw is not running. Do not decrement count in poll, do it in ioctl, where data are actually read.

* Misc: phantom, add compat ioctlJiri Slaby2008-04-291-4/+20
| | | | | | | | | | | Openhaptics uses pointers in _IOC() macros, implement compat for them. Also add _IOC alternatives which are not 32/64 bit dependent (structures passed through aren't yet) -- libphantom will use them.

* phantom: don't grab other devicesJiri Slaby2008-02-061-3/+4
| | | | | | | | | | | Specify also sub pci ids to not grab devices with properly set sub ids. This devices has these set (unset) to the same as (plx 9050) ids.

* Misc: phantom, improved data passingJiri Slaby2007-10-191-18/+76
| | | | | | | | | | This new version guarantees amb_bit switch in small enough intervals, so that the device won't stop working in the middle of a movement anymore. However it preserves old (openhaptics) functionality.

* phantom: move to unlocked_ioctlJiri Slaby2007-05-241-4/+14
