262099e94a
This change replaces kzfree with kfree as kzfree has been renamed. While moving to the latest 5.10 tip, additional small changes were required to resolve compilation issues: set_dma_ops has moved from dma-mapping to dma-map-ops header. This change includes the new header file required. drm_panel_add returns void, this change removes the expected return value check. drm_prime_pages_to_sg takes an additional parameter. This change passes in the drm_device pointer the function is looking for. Remove an unused variable in sde_crtc vblank function.
