X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8824ae2de876f7e73ca64937dca88e558db5b681;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git ALSA: usb-audio: constify usb_device_id. usb_device_id are not supposed to change at runtime. All functions working with usb_device_id provided by work with const usb_device_id. So mark the non-const structs as const.
