Clang warns (or errors with CONFIG_WERROR): drivers/gpu/drm/panthor/panthor_sched.c:2048:6: error: variable 'csg_mod_mask' set but not used [-Werror,-Wunused-but-set-variable] 2048 | u32 csg_mod_mask = 0, free_csg_slots = 0; | ^ 1 error generated. The variable is an artifact left over from refactoring that occurred during the development of the initial series for this driver. Remove it to resolve the warning.
