[alsa-devel] [PATCH][next] ASoC: Intel: bytcht_es8316: make mic_name static, reduces object code size

[Colin King]

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

Don't populate the const array mic_name on the stack but instead make
it static. Makes the object code smaller by 28 bytes:

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)
