ALSA: ad1816a: Fix assignment in if condition
ISA AD1816A driver code contains lots of assignments in if condition, which is a bad coding style that may confuse readers and occasionally lead to bugs. This patch is merely for coding-style fixes, no functional changes. Link: https://lore.kernel.org/r/20210608140540.17885-6-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
