X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=980092efd497dd691438e086dd929c1b04ecc529;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git power: supply: constify attribute_group structures. attribute_groups are not supposed to change at runtime. All functions working with attribute_groups provided by work with const attribute_group. So mark the non-const structs as const.
