So, an alternative solution could be for hdac_unsolq_flush() to check both = dev !=3D NULL and device_is_attached(dev). Still could be somewhat racy. Regarding the shutdown method -- yes, there is no need to detach HDA driver during shutdown. At the same time, there is no need to keep it attached too. So, I am ambivalent about that. --=20 You are receiving this mail because: You are the assignee for the bug.=
