Subject: [PATCH] ASoC: rt1011: make array pd static const, makes object smaller
Git-commit: 2b70d5776e8b173e3b36a2ef63d94428c6a80e1f
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 100 bytes.
