Subject: Input: gpio-keys - use IRQF_SHARED
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=558a5e296a02266ef43d6e933ee35df9976de987;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

Input: gpio-keys - use IRQF_SHARED

There is nothing that disallows gpio-keys to share it's IRQ line
w/ other drivers. Make it use IRQF_SHARED in request_irq().

An example of other driver with which I'd like to share IRQ line
for GPIO buttons is ledtrig-gpio.
