2017-01-26gpiolib: Convert fwnode_get_named_gpiod() to configure GPIOAndy Shevchenko2-17/+3
Make fwnode_get_named_gpiod() consistent with the rest of gpiod_get() like API, i.e. configure GPIO pin immediately after request. Besides obvious clean up it will help to configure pins based on firmware provided resources.

Declare device_type structures as const as they are only stored in the type field of a device structure. This field is of type const, so add const to declaration of device_type structures.

Commit 6480af4915d6 ("power_supply: wm97xx_battery: use power_supply_get_drvdata") made wm97xx platform data mandatory, although it's still optional. This patch fixes an oops during driver probe on one of my MIPS boards with a wm9712.

2017-01-22Input: pwm-beeper - fix race when suspendingDmitry Torokhov1-3/+18
Usually userspace sends SND_BELL and SND_TONE events, and by the time pwm_beeper_suspend() runs userpsace is already frozen, but theoretically in-kernel users may send these events too, and that may cause pwm_beeper_event() scheduling another work after we canceled it. Let's introduce a "suspended" flag and check it in pwm_beeper_event() to avoid this race.

2017-01-21Input: soc_button_array - debounce the buttonsHans de Goede1-0/+2
The soc_button_array driver was initializing (kzalloc) the debounce_interval value to 0, leading to no debouncing at all, while the buttons are simple mechanical switches. This commit sets debounce_interval to 50ms to avoid spurious button press reports both on press and release of the button. Note 50ms may seem like a lot but soc_button_array is typically used with cheap tablets, with not so great buttons. I tried 10ms on my tablet and it is not enough, where as 50ms works well.
