Subject: Input: gpio_keys - switch to using threaded IRQs
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7e2ecdf438bb479e2b4667fc16b1a84d6348da04;p=linux-beck.git

Input: gpio_keys - switch to using threaded IRQs

Use a threaded interrupt handler in order to permit the handler to use
a GPIO driver that causes things like I2C transactions being done inside
the handler context.
