[PATCH] iio:adc:at91-sama5d2: make array startup_lookup static to reduce code size

From: Colin King
Date: Fri Jul 07 2017 - 12:10:10 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Making the const array startup_lookup static rather having it on the
stack saves 69 bytes. Add in missing int specifier to clean up a
checkpatch warning.
