Revision ad537b822577fcc143325786cd6ad50d7b9df31c authored by Bartosz Golaszewski on 23 June 2017, 11:45:16 UTC, committed by Linus Walleij on 29 June 2017, 09:33:46 UTC
GPIOEVENT_REQUEST_BOTH_EDGES is not a single flag, but a binary OR of
GPIOEVENT_REQUEST_RISING_EDGE and GPIOEVENT_REQUEST_FALLING_EDGE.
The expression 'le->eflags & GPIOEVENT_REQUEST_BOTH_EDGES' we'll get
evaluated to true even if only one event type was requested.
Fix it by checking both RISING & FALLING flags explicitly.
