| Subject | [PATCH] drm: bridge: dw-hdmi: constify snd_pcm_ops structures |
| Message-ID | <uctKW-3Wi-11@gated-at.bofh.it> |
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.
