Subject: [PATCH] ALSA: hda: constify attribute_group structures.
Git-commit: a5a041b6b50bcaf96f96e5db4850d11006d61d26
Patch-mainline: v4.13-rc1
References: bsc#1121278
attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by <linux/device.h> work with const
attribute_group. So mark the non-const structs as const.
File size before:

File size After adding 'const':
text data bss dec hex filename
1035 544 0 1579 62b sound/pci/hda/hda_sysfs.o
