ALSA: drivers: Clean up with new procfs helpers
Simplify the proc fs creation code with new helper functions, snd_card_ro_proc_new() and snd_card_rw_proc_new(). Just a code refactoring and no functional changes. Reviewed-by: Jaroslav Kysela <perex@perex.cz> Signed-off-by: Takashi Iwai <tiwai@suse.de>
