a=openpgp; fpr=4880B8C9BD0E5106FC070F4F7B3C391EFEA93624 Content-Transfer-Encoding: 8bit snd_cs46xx_proc_init() stores the chip in the private data of the five region entries, but snd_cs46xx_io_read() reads that back as the region, so a read of /proc/asound/cardN/CS46xx_BA0 and friends copies from whatever sits at the region's offset in struct snd_cs46xx instead of the mapped registers. Store the region.
