Subject: ALSA: mips: constify snd_pcm_ops structures
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=915a38d324d23f4fa53306a3a834f54a9f6da17c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ALSA: mips: constify snd_pcm_ops structures

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.
