SubjectApplied "ASoC: codecs: ad193x: make two arrays static const, makes object smaller" to the asoc tree
Date
The patch

ASoC: codecs: ad193x: make two arrays static const, makes object smaller

has been applied to the asoc tree at

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4

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: codecs: ad193x: make two arrays static const, makes
object smaller

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)
