Subject: [alsa-devel] [PATCH] ASoC: rt1308: make array pd static const, makes object smaller
Date: Sat, 7 Sep 2019 08:46:34 +0100 [thread overview]
Message-ID: <20190907074634.22144-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Don't populate the array pd on the stack but instead make it
static const. Makes the object code smaller by 82 bytes.
Before:
text data bss dec hex filename
26548 7288 64 33900 846c sound/soc/codecs/rt1308.o
After:
text data bss dec hex filename
26370 7384 64 33818 841a sound/soc/codecs/rt1308.o
(gcc version 9.2.1, amd64)
