2014-10-14input: edt-ft5x06: replace strnicmp with strncasecmpRasmus Villemoes
The kernel used to contain two functions for length-delimited, case-insensitive string comparison, strnicmp with correct semantics and a slightly buggy strncasecmp. The latter is the POSIX name, so strnicmp was renamed to strncasecmp, and strnicmp made into a wrapper for the new strncasecmp to avoid breaking existing users. To allow the compat wrapper strnicmp to be removed at some point in the future, and to avoid the extra indirection cost, do s/strnicmp/strncasecmp/g.

Commit b5ada4600dfd ("drivers/rtc/rtc-cmos.c: fix compilation warning when !CONFIG_PM_SLEEP") broke wakeup from S5 by making cmos_poweroff a nop unless CONFIG_PM_SLEEP was defined. Fix this by restricting the #ifdef to cmos_resume and restoring the old dependency on CONFIG_PM for cmos_suspend and cmos_poweroff.

Checking for any non-zero value in the interrupt handler as well is just as correct and lets the compiler know what we are doing, without needing a bogus initialization.

2014-10-14rtc: max77686: fail to probe if no RTC regmap irqchip is setJavier Martinez Canillas
The max77686 mfd driver adds a regmap IRQ chip which creates an IRQ domain that is used to map the virtual RTC alarm1 interrupt. The RTC driver assumes that this will always be true since the PMIC IRQ is a required property according to the max77686 DT binding doc. If an "interrupts" property is not defined for a max77686 PMIC, then the mfd probe function will fail and the RTC platform driver will never be probed. But even when it is not possible to probe the rtc-max77686 driver without a regmap IRQ chip, it's better to explicitly check if the IRQ chip data is not NULL and gracefully fail instead of getting an OOPS.

2014-10-14rtc: max77686: remove dead code for SMPL and WTSRJavier Martinez Canillas
The MAX77686 RTC chip has two features called SMPL (Sudden Momentary Power Loss) and WTSR (Watchdog Timeout and Software Resets). Support for these features seems to be implemented in the driver but compilation is disabled using a C pre-processor conditional. This code has been disabled since the driver was original merged in commit fca1dd031a28 ("rtc: max77686: add Maxim 77686 driver"). So, since this code has never been built, let's just remove it.

2014-10-14rtc: max77686: Allow the max77686 rtc to wakeup the systemDoug Anderson
This series add support for the Real Time clock present in the Maxim 77802 Power Managment IC. The version number is quite high because it previously was part of a bigger series [0] that aimed to add support for all the devices in the max77802 PMIC. But now that the max77802 dependencies were already merged for 3.17, the series were split but I kept the version numbering. While working on the max77802 rtc support a lot of feedback was given and the issues pointed out also apply to a driver for a similar PMIC RTC (max77686). So patches 01/06 to 05/06 in the series are cleanups for the max77686 driver and patch 06/06 adds the support for the max77802 RTC. The series were tested on an Exynos5250 Snow (max77686) and Exynos5420 Peach Pit (max77802) machines. This patch (of 6): The max77686 includes an RTC that keeps power during suspend. It's convenient to be able to use it as a wakeup source.

2014-10-10net: systemport: avoid unbalanced enable_irq_wake callsFlorian Fainelli
Multiple enable_irq_wake() calls will keep increasing the IRQ wake_depth, which ultimately leads to the following types of situation: 1) enable Wake-on-LAN interrupt w/o password 2) enable Wake-on-LAN interrupt w/ password 3) enable Wake-on-LAN interrupt w/o password 4) disable Wake-on-LAN interrupt After step 4), SYSTEMPORT would always wake-up the system no matter what wake-up device we use, which is not what we want. Fix this by making sure there are no unbalanced enable_irq_wake() calls. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-10-10net: bcmgenet: fix off-by-one in incrementing read pointerFlorian Fainelli
Commit b629be5c8399d7c423b92135eb43a86c924d1cbc ("net: bcmgenet: check harder for out of memory conditions") moved the increment of the local read pointer *before* reading from the hardware descriptor using dmadesc_get_length_status(), which creates an off-by-one situation. Fix this by moving again the read_ptr increment after we have read the hardware descriptor to get both the control block and the read pointer back in sync.

2014-10-10mlx4: fix race accessing page->_countEric Dumazet
This is illegal to use atomic_set(&page->_count, ...) even if we 'own' the page. Other entities in the kernel need to use get_page_unless_zero() to get a reference to the page before testing page properties, so we could loose a refcount increment.
