    Subject[PATCH AUTOSEL 5.4 11/15] drm/amdkfd: fix a memory leak issue
    Date
    From: Dennis Li <Dennis.Li@amd.com>

    [ Upstream commit 087d764159996ae378b08c0fdd557537adfd6899 ]

    In the resume stage of GPU recovery, start_cpsch will call pm_init
    which set pm->allocated as false, cause the next pm_release_ib has
    no chance to release ib memory.

    Add pm_release_ib in stop_cpsch which will be called in the suspend
    stage of GPU recovery.
