Subject: ALSA: intel8x0: constify ac97_pcm structures
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=668d06165c4a7d5bbb29fadd3e1b2d610b73c456;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ALSA: intel8x0: constify ac97_pcm structures

ac97_pcm are not supposed to change at runtime. All functions
working with ac97_pcm provided by <sound/ac97_codec.h> work with
const ac97_pcm. So mark the non-const structs as const.
