Subject: [PATCH] ASoC: rt5514: make array div static const, makes object smaller
Date: Sun, 1 Aug 2021 07:40:23 +0100 [thread overview]
Message-ID: <20210801064023.138359-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Don't populate the array div on the stack but instead it
static const. Makes the object code smaller by 48 bytes.
Before:
text data bss dec hex filename
53894 16368 128 70390 112f6 ./sound/soc/codecs/rt5514.o
After:
text data bss dec hex filename
53750 16464 128 70342 112c6 ./sound/soc/codecs/rt5514.o
(gcc version 10.2.0)
