Subject[PATCH] iio:adc:at91-sama5d2: make array startup_lookup static to reduce code size
Date
From: Colin Ian King <colin.king@canonical.com>

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.

Before:

After:
