Subject: [PATCH] iio: adc: at91: make array startup_lookup static
Date: Mon, 10 Jul 2017 18:46:54 +0100 [thread overview]
Message-ID: <20170710174654.17271-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Don't populate array startup_lookup on the stack but instead make
it static. Makes the object code smaller.
Before:
text data bss dec hex filename
21754 5440 128 27322 6aba drivers/iio/adc/at91_adc.o
After:
text data bss dec hex filename
21613 5496 128 27237 6a65 drivers/iio/adc/at91_adc.o
