SubjectApplied "ASoC: TSCS42xx: make const array norm_addrs static, reduces object code size" to the asoc tree
Date
The patch

ASoC: TSCS42xx: make const array norm_addrs static, reduces object code size

has been applied to the asoc tree at

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Subject: [PATCH] ASoC: TSCS42xx: make const array norm_addrs static, reduces
object code size

Don't populate the const array norm_addrs on the stack, instead make it
static. Makes the object code smaller by over 230 bytes. Also re-format
array data as the insertion of the static keywork made the first line
overly long.

Before:
text data bss dec hex filename
53780 34752 256 88788 15ad4 linux/sound/soc/codecs/tscs42xx.o

After:
text data bss dec hex filename
53461 34840 256 88557 159ed linux/sound/soc/codecs/tscs42xx.o

(gcc version 7.2.0 x86_64)
