ALSA: ice1712: Delete unreachable code in aureon_add_controls()
If the check (id != 0x41) fails, then id == 0x41 and the other check in 'else' branch also fails: id & 0x0F = 0b01000001 & 0b00001111 = 0b00000001. Found by Linux Verification Center (linuxtesting.org) with SVACE. Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Signed-off-by: Dmitry Fomin <fomindmitriyfoma@mail.ru> Link: https://lore.kernel.org/r/20230225184322.6286-2-fomindmitriyfoma@mail.ru Signed-off-by: Takashi Iwai <tiwai@suse.de>
