{sigh}

I now get this build error with this patch applied:

 CC [M]  drivers/firmware/google/gsmi.o
drivers/firmware/google/gsmi.c: In function ‘gsmi_die_callback’:
drivers/firmware/google/gsmi.c:660:16: error: ‘DIE_NMIWATCHDOG’ undeclared (first use in this function)
drivers/firmware/google/gsmi.c:660:16: note: each undeclared identifier is reported only once for each function it appears in
make[3]: *** [drivers/firmware/google/gsmi.o] Error 1


Also, I had to hand edit the drivers/firmware/Makefile and Kconfig parts
of this patch to get it to apply, care to respin it against the
linux-next tree so I don't have to do that next time around?

thanks,

greg k-h
