ALSA: pcm: constify function local and read-only table
In a function snd_pcm_hw_params_choose(), target parameters are arranged into a table. Though each entry of this table is read-only, they don't have const qualifier. This commit adds the qualifier. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
