ALSA: hda: constify attribute_group structures.
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: text data bss dec hex filename 995 608 0 1603 643 sound/pci/hda/hda_sysfs.o File size After adding 'const': text data bss dec hex filename 1035 544 0 1579 62b sound/pci/hda/hda_sysfs.o Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
