Subject: Input: wm831x-ts - allow IRQ flags to be specified
X-Git-Tag: firefly_0821_release~176^2~541^2~424
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=acad9853b95df6a3887f52e0ec88e4a77119ee28;p=firefly-linux-kernel-4.4.55.git

Input: wm831x-ts - allow IRQ flags to be specified

This allows maximum flexibility for configuring the direct GPIO based
interrupts.
