Description

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix mismatched unlock for DMUB HW lock in HWSS fast path [Why] The evaluation for whether we need to use the DMUB HW lock isn't the same as whether we need to unlock which results in a hang when the fast path is used for ASIC without FAMS support. [How] Store a flag that indicates whether we should use the lock and use that same flag to specify whether unlocking is needed.
