Commit d1d1173 ("disp: msm: update msm_gem ops and remove unused
drm_driver callbacks") Update msm_gem and msm_drv to comply with
latest 5.15 kernel.Modify dma_buf_vmap() and dma-buf's vmap callback
to use truct dma_buf_map. Rename dma_resv_get_excl_rcu to _unlocked.
Remove deprecated GEM and PRIME callbacks.
