Subject: firmware/efi: Constify attribute_group structures
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3ad6bd7c0a1c49a78d00001cfda3d474c23bc354;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

firmware/efi: Constify attribute_group structures

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