Subject: [PATCH] ASoC: rt1308: make array pd static const, makes object smaller
Git-commit: 13ab0d1ab8ae4d1b3b247fd5caec2c10e35c7269
Patch-mainline: v5.4-rc1
References: jsc#SLE-16518

Don't populate the array pd on the stack but instead make it
static const. Makes the object code smaller by 82 bytes.

Before: text	   data	    bss	    dec	    hex	filename  26548	   7288	     64	  33900	   846c	sound/soc/codecs/rt1308.o

After: text	   data	    bss	    dec	    hex	filename  26370	   7384	     64	  33818	   841a	sound/soc/codecs/rt1308.o
