ALSA: usb-audio: Fix superfluous autosuspend recovery
The change to restore the autosuspend from the disabled state uses a wrong check: namely, it should have been the exact comparison of the quirk_type instead of the bitwise and (&). Otherwise it matches wrongly with the other quirk types. Although re-enabling the autosuspend for the already enabled device shouldn't matter much, it's better to fix the unbalanced call. Fixes: 9799110825db ("ALSA: usb-audio: Disable USB autosuspend properly in setup_disable_autosuspend()") Cc: <stable@vger.kernel.org> Link: https://lore.kernel.org/r/s5hr1flh9ov.wl-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
