Don't populate the const arrays on the stack but instead make
it static. Makes the object code smaller, for example:

Before:
   text    data     bss     dec     hex filename
  14107    8832     224   23163    5a7b bytcht_es8316.o

After:
   text    data     bss     dec     hex filename
  14015    8896     224   23135    5a5f bytcht_es8316.o

(gcc version 8.2.0 x86_64)

V2: also fix up bytcr_rt5640.c and bytcr_rt5651.c, thanks to
Pierre-Louis Bossart for noticing these two.

The patch

   ASoC: Intel: make const arrays 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: Intel: make const arrays static, reduces object code
 size

Don't populate the const arrays on the stack but instead make
it static. Makes the object code smaller, for example:

Before:
   text    data     bss     dec     hex filename
  14107    8832     224   23163    5a7b bytcht_es8316.o

After:
   text    data     bss     dec     hex filename
  14015    8896     224   23135    5a5f bytcht_es8316.o

(gcc version 8.2.0 x86_64)
