--- Comment #20 from Chen Gang <gang.chen.5i5j at gmail dot com> --- (In reply to Chen Gang from comment #19) > I build linux kernel with allyesconfig under x86_64 for linux-next tree > 20160122. I can find some related cases for BUG28901 (but they are not quite > much), one case is below: > > CC drivers/acpi/sbshc.o > In file included from drivers/acpi/sbshc.c:17:0: > drivers/acpi/sbshc.h:17:17: warning: ‘SMBUS_PEC’ defined but not used > [-Wunused-const-variable] > static const u8 SMBUS_PEC = 0x80; > ^~~~~~~~~ Oh, sorry, this case is not suitable, it is -Wunused-const-variable. But my opinion still like what I said in comment #19. Thanks.
