6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@xxxxxxx>
commit 66a0a2b0473c39ae85c44628d14e4366fdc0aa0d upstream.
Fix a brown paper bag bug I introduced at converting to the standard
iter helper; the arguments were wrongly passed and have to be
swapped.
Fixes: 9b5f8ee43e48 ("ALSA: sh: Use standard helper for buffer accesses")
