The constants of enum snd_efw_grp_type is for struct snd_efw_phys_grp.type. But this member is 1 byte. Although the value is between 0x00-0xff, a constant has 0x10000. This constant is meaningless. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
