Subject: usb: hcd: constify attribute_group structures.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=60da70d3e5731832f0482db8686c91c80d9e4bb5;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

usb: hcd: 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.
