[PATCH] drm/radeon: remove three set but not used variable

From: yu kuai
Date: Thu Dec 26 2019 - 07:08:40 EST


Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/radeon/radeon_atombios.c: In function
âradeon_get_atom_connector_info_from_object_tableâ:
drivers/gpu/drm/radeon/radeon_atombios.c:651:26: warning: variable
âgrph_obj_numâ set but not used [-Wunused-but-set-variable]
drivers/gpu/drm/radeon/radeon_atombios.c:651:13: warning: variable
âgrph_obj_idâ set but not used [-Wunused-but-set-variable]
drivers/gpu/drm/radeon/radeon_atombios.c:573:37: warning: variable
âcon_obj_typeâ set but not used [-Wunused-but-set-variable]

They are never used, and so can be removed.
