Subject: [PATCH] drm: i915: sysfs: constify attribute_group structures.
Git-commit: 0a7a0986559d85c9926cbe5b1570212e09008a7c
Patch-mainline: v4.14-rc1
References: FATE#322643 bsc#1055900
attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by <linux/sysfs.h> work with const
attribute_group. So mark the non-const structs as const.

File size After adding 'const':
text data bss dec hex filename
4196 928 0 5124 1404 drivers/gpu/drm/i915/i915_sysfs.o
