stable inclusion from stable-5.10.45 commit 9e8c2af010463197315fa54a6c17e74988b5259c bugzilla: 109305 CVE: NA -------------------------------- [ Upstream commit c5699e2d ] [Why] On resume we perform DMUB hw_init which allocates memory: dm_resume->dm_dmub_hw_init->dc_dmub_srv_create->kzalloc That results in memory leak in suspend/resume scenarios. [How] Allocate memory for the DC wrapper to DMUB only if it was not allocated before. No need to reallocate it on suspend/resume.
