I don't see many of the problems you report, even if I build the files with W=1. It is odd, since reports such as drivers/mfd/asic3.c:941:23: error: unused variable 'asic' are real, but I just don't see that. If I build that file, I see that it builds with -Wno-unused-but-set-variable, due to Makefile:KBUILD_CFLAGS += $(call cc-disable-warning, unused-but-set-variable) The override in scripts/Makefile.extrawarn doesn't seem to work even though it adds "-Wunused-but-set-variable" to the compile flags. And if I remove "-Wno-unused-but-set-variable" from Makefile I still don't get the error/warning. Confused. I must be missing something, but what ? Thanks, Guenter
