* drivers/memstick/core/mspro_block: use kmemdupMuhammad Falak R Wani2016-05-241-2/+1
| | | | | | | | | | | | Use kmemdup when some other buffer is immediately copied into allocated region. It replaces call to allocation followed by memcpy, by a single call to kmemdup.

* rtsx_usb_ms: use schedule_timeout_idle() in polling loopOleksandr Natalenko2016-05-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | First version of this patch has already been posted to LKML by Ben Hutchings ~6 months ago, but no further action were performed. Ben's original message: : rtsx_usb_ms creates a task that mostly sleeps, but tasks in : uninterruptible sleep still contribute to the load average (for : bug-compatibility with Unix). A load average of ~1 on a system that : should be idle is somewhat alarming. : : Change the sleep to be interruptible, but still ignore signals.

* | x86: remove pointless uaccess_32.h complexityLinus Torvalds2016-05-221-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I'm looking at trying to possibly merge the 32-bit and 64-bit versions of the x86 uaccess.h implementation, but first this needs to be cleaned up. For example, the 32-bit version of "__copy_to_user_inatomic()" is mostly the special cases for the constant size, and it's actually never relevant. Every user except for one aren't actually using a constant size anyway, and the one user that uses it is better off just using __put_user() instead. So get rid of the unnecessary complexity. [ The same cleanup should likely happen to __copy_from_user_inatomic() as well, but that one has a lot more users that I need to take a look at first ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

When we set the time by writing into SET_TIME_WRITE Register and immediately try to read the rtc time from CURRENT_TIME register, the previous old value is returned instead of the new loaded time. This is because RTC takes nearly 1 sec to update the new loaded value into the CURRENT_TIME register. This behaviour is expected in our RTC IP. This patch updates the driver to read the current time from SET_TIME_WRITE register instead of CURRENT_TIME when rtc time is requested within an 1sec period after setting the RTC time. Doing so will ensure the correct time is given to the user. Since there is a delay of 1sec in updating the CURRENT_TIME we are loading set time +1sec while programming the SET_TIME_WRITE register, doing this will give correct time without any delay when read from CURRENT_TIME.

This change will apply to the RTC driver that supports both DA9052 and DA9053 PMICs. A problem could occur with the existing RTC driver if: A system is started from a cold boot using the PMIC RTC IRQ to initiate a power on operation. For instance, if an RTC alarm is used to start a platform from power off. The existing driver IRQ is requested before the device has been properly registered. i.e. ret = da9052_request_irq() comes before rtc->rtc = devm_rtc_device_register(); In this case, an interrupt exists before the device has been registered and the IRQ handler can be called immediately: this can happen be before the memory for rtc->rtc has been allocated. The IRQ handler da9052_rtc_irq() contains the function call: rtc_update_irq(rtc->rtc, 1, RTC_IRQF | RTC_AF); which in turn tries to access the unavailable rtc->rtc. The fix is to reorder the functions inside the RTC probe. The IRQ is requested after the RTC device resource has been registered so that da9052_request_irq() is the last thing to happen.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Handle the Oscillator Failure (OF) bit on each read of date-time. If the OF is set, an error is returned (-EINVAL) instead of the date-time. The OF bit is cleared each time the date is set. Signed-off-by: Mylène Josserand <mylene.josserand@free-electrons.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | To enable the wakealarm, the device must be able to wakeup. This is done by setting the device wakeup capability to true with 'device_init_wakeup' function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previous 'commit c3b79770e51a ("Expire alarms after the time is set")' and 'commit 48e9766726eb ("remove disabled alarm functionality")' removed the alarm support because the alarm irq was not functional. Add the alarm IRQ functionality with newer functions than previous code. Tested with 'rtctest' and the alarm is functional.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver used i2c_transfer methods to read and set date/time. The smbus methods should be used.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Many drivers are defining a DRV_VERSION. This is often only used for MODULE_VERSION and sometimes to print an info message at probe time. This is kind of pointless as they are all versionned with the kernel anyway. Also the core will print a message when a new rtc is found.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The OMAP mailbox driver is used by clients to communicate with remote processors in general. The mailbox clients are expected to have stopped communicating with these remote processors during a system suspend. The OMAP mailbox fifos are expected to not have any messages as such. Add a check for any pending unprocessed messages in the suspend callback, to detect any communication protocol issues of the mailbox clients. The system suspend is aborted if any messages are found.
