Subject: [PATCH] ASoC: SOF: compr: Mark snd_compress_ops static
Git-commit: e7c799e76f070b4ac13498e532574466064ad6a5
Patch-mainline: v5.18-rc1
References: jsc#PED-850

Functions won't be directly used outside of compress.c file
so mark them as static.

This will also fix warnings reported by kernel test robot:

>> sound/soc/sof/compress.c:91:5: warning: no previous prototype for
function 'sof_compr_open' [-Wmissing-prototypes]
   int sof_compr_open(struct snd_soc_component *component,
       ^
   sound/soc/sof/compress.c:91:1: note: declare 'static' if the function
is not intended to be used outside of this translation unit
   int sof_compr_open(struct snd_soc_component *component,

Fixes: 6324cf901e14 ("SoC: SOF: compr: Add compress ops implementation")
