Jani Nikula b5dacc8fb5 drm/i915: fix header test with GCOV ... $(CC) with $(CFLAGS_GCOV) assumes the output filename with .gcno suffix appended is writable. This is not the case when the output filename is /dev/null: HDRTEST drivers/gpu/drm/i915/display/intel_frontbuffer.h /dev/null:1:0: error: cannot open /dev/null.gcno HDRTEST drivers/gpu/drm/i915/display/intel_ddi.h /dev/null:1:0: error: cannot open /dev/null.gcno make[5]: *** [../drivers/gpu/drm/i915/Makefile:307: drivers/gpu/drm/i915/display/intel_ddi.hdrtest] Error 1 make[5]: *** Waiting for unfinished jobs.... make[5]: *** [../drivers/gpu/drm/i915/Makefile:307: drivers/gpu/drm/i915/display/intel_frontbuffer.hdrtest] Error 1 Filter out $(CFLAGS_GVOC) from the header test $(c_flags) as they don't make sense here anyway.
