ALSA: pcm: 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 9781 240 8 10029 272d sound/core/pcm.o File size After adding 'const': text data bss dec hex filename 9813 176 8 9997 270d sound/core/pcm.o Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
