Subject: [PATCH v2 3/5] Staging: iio: adt7316: Switch irq_flags to a local variable

There is no need to store irq_flags into the structure as it
is always set to the same thing. Hence switch irq_flags to a
local variable.

Applied to the togreg branch of iio.git and pushed out as testing
for the autobuilders to play with it.
