Subject: [PATCH] iio:adc:at91-sama5d2: make array startup_lookup static to reduce code size
Date: Fri, 7 Jul 2017 17:08:35 +0100 [thread overview]
Message-ID: <20170707160835.19080-1-colin.king@canonical.com> (raw)
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.
