If CONFIG_BUG=n __WARN_printf won't be defined leading to the below build failure. The double underscores should have told us to steer clear of it anyway. drivers/gpu/drm/i915/intel_display.c: In function ‘assert_pll’: drivers/gpu/drm/i915/intel_display.c:1027:2: error: implicit declaration of function ‘__WARN_printf’ [-Werror=implicit-function-declaration] I915_STATE_WARN(cur_state != state, Use WARN(1, ...) instead. It handles CONFIG_BUG=n gracefully and, with the constant condition, a sane compiler should reduce it to __WARN_printf.
