Subject: [alsa-devel] [PATCH] ASoC: codecs: ad193x: make two arrays static const, makes object smaller
Date: Fri, 6 Sep 2019 17:14:04 +0100 [thread overview]
Message-ID: <20190906161404.1440-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Don't populate the arrays on the stack but instead make them
static const. Makes the object code smaller by 37 bytes.
Before:
text data bss dec hex filename
16253 7200 0 23453 5b9d sound/soc/codecs/ad193x.o
After:
text data bss dec hex filename
16056 7360 0 23416 5b78 sound/soc/codecs/ad193x.o
(gcc version 9.2.1, amd64)
