Hello Dmitry Baryshkov,

The patch 6a4bc73915af: "drm/msm/dpu: drop separate
dpu_core_perf_tune overrides" from Jul 30, 2023 (linux-next), leads
to the following Smatch static checker warning:

	drivers/gpu/drm/msm/disp/dpu1/dpu_core_perf.c:295 _dpu_core_perf_get_core_clk_rate()
	error: uninitialized symbol 'clk_rate'.
