From 66291b6adb66dd3bc96b0f594d88c2ff1300d95f Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 26 Jul 2021 08:26:56 +0200 Subject: 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.
