From: Oliver Neukum <oneukum@xxxxxxxx> commit 21e3d6c81179bbdfa279efc8de456c34b814cfd2 upstream. I've got a report about a UAS drive enclosure reporting back Sense: Logical unit access not authorized if the drive it holds is password protected. While the drive is obviously unusable in that state as a mass storage device, it still exists as a sd device and when the system is asked to perform a suspend of the drive, it will be sent a SYNCHRONIZE CACHE. If that fails due to password protection, the error must be ignored.
