charset=UTF-8 Content-type: text/plain Content-Transfer-Encoding: 8bit From: Guenter Roeck The drm_test_rect_calc_hscale and drm_test_rect_calc_vscale unit tests intentionally trigger warning backtraces by providing bad parameters to the tested functions. What is tested is the return value, not the existence of a warning backtrace. Suppress the backtraces to avoid clogging the kernel log and distraction from real problems.
