Revision 558a5e296a02266ef43d6e933ee35df9976de987 authored by Dmitry Eremin-Solenikov on 03 November 2009, 06:04:18 UTC, committed by Dmitry Torokhov on 03 November 2009, 06:12:37 UTC 
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.
