Subject: ALSA: drivers: mpu401: constify pnp_device_id
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1491c68a2248747de0bfb83350c5096954b40dce;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ALSA: drivers: mpu401: constify pnp_device_id

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