Subject: drm: bridge: dw-hdmi: constify snd_pcm_ops structures
Git-commit: b27cc7b5b728c62a8d7fe92c159a4d8daacd064a
Patch-mainline: v4.14-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

snd_pcm_ops are not supposed to change at runtime. All functions
working with snd_pcm_ops provided by <sound/pcm.h> work with
const snd_pcm_ops. So mark the non-const structs as const.
