1. Fix build warning message in mtk_disp_ovl_adaptor.c
>> drivers/gpu/drm/mediatek/mtk_disp_ovl_adaptor.c:415:10:
warning: cast to smaller integer type 'enum mtk_ovl_adaptor_comp_type'
from 'const void *' [-Wvoid-pointer-to-enum-cast]
type = (enum mtk_ovl_adaptor_comp_type)of_id->data;
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 warning generated.
2. Also fix the same warning message in mtk_drm_drv.c
>> drivers/gpu/drm/mediatek/mtk_drm_drv.c:832:15:
warning: cast to smaller integer type 'enum mtk_ddp_comp_type'
from 'const void *' [-Wvoid-pointer-to-enum-cast]
comp_type = (enum mtk_ddp_comp_type)of_id->data;
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
