commit 66291b6adb66dd3bc96b0f594d88c2ff1300d95f upstream.
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.
