[PATCH] ASoC: mediatek: mt8195: make array adda_dai_list static const

[PATCH] ASoC: mediatek: mt8195: make array adda_dai_list static const

[Colin King]

From: Colin Ian King <colin.king@canonical.com>

Don't populate the array adda_dai_list on the stack but instead it
static const. Also makes the object code smaller by 33 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
  28271	  11640	      0	  39911	   9be7	mt8195/mt8195-dai-adda.o

After:
   text	   data	    bss	    dec	    hex	filename
  28142	  11736	      0	  39878	   9bc6	mt8195/mt8195-dai-adda.o

(gcc version 11.2.0)

      commit: ce3f9357638720f4a78f6a6e481941c37f33bceb

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
