- After making the required changes
This patch fixes some of the warnings while building kernel Docs:
./drivers/gpu/drm/amd/display/dc/inc/hw/mpc.h:547: warning: Function parameter or struct member 'read_mpcc_state' not described in 'mpc_funcs'
./drivers/gpu/drm/amd/display/dc/inc/hw/mpc.h:547: warning: Function parameter or struct member 'mpc_init_single_inst' not described in 'mpc_funcs'
./drivers/gpu/drm/amd/display/dc/inc/hw/mpc.h:547: warning: Function parameter or struct member 'get_mpcc_for_dpp_from_secondary' not described in 'mpc_funcs'
./drivers/gpu/drm/amd/display/dc/inc/hw/mpc.h:547: warning: Function parameter or struct member 'get_mpcc_for_dpp' not described in 'mpc_funcs'
./drivers/gpu/drm/amd/display/dc/inc/hw/mpc.h:547: warning: Function parameter or struct member 'wait_for_idle' not described in 'mpc_funcs'
./drivers/gpu/drm/amd/display/dc/inc/hw/mpc.h:547: warning: Function parameter or struct member 'assert_mpcc_idle_before_connect' not described in 'mpc_funcs'
by adding descriptions to these struct members
