stable inclusion from stable-5.10.79 commit 42681b90c4db8bf29fc2cc93789ec093bb209296 bugzilla: 185793 https://gitee.com/openeuler/kernel/issues/I4K65C
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
commit 05c8f1b67e67dcd786ae3fe44492bbc617b4bd12 upstream.
These drive enclosures have firmware bugs that make it impossible to mount a new virtual ISO image after Linux ejects the old one if the device is locked by Linux. Windows bypasses this problem by the fact that they do not lock the device. Add a quirk to disable device locking for these drive enclosures.
