How do you build your images ? 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
