Subject: backlight: pwm_bl: Make of_device_ids const
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=62cdfe658535c39003d4d1b9d7f9b5a23a0db6bf;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

backlight: pwm_bl: Make of_device_ids const

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