ALSA: aoa: Fix I2S device accounting
i2sbus_add_dev() is supposed to return the number of probed devices, i.e. either 1 or 0. However, i2sbus_add_dev() has one error handling that returns -ENODEV; this will screw up the accumulation number counted in the caller, i2sbus_probe(). Fix the return value to 0 and add the comment for better understanding for readers. Fixes: f3d9478b2ce4 ("[ALSA] snd-aoa: add snd-aoa") Link: https://lore.kernel.org/r/20221027065233.13292-1-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
