I think the better fix is for those two routines to be defined for CONFIG_PRINTK=n, but return NULL and zero respectively. And the opal code could skip registering the region when they return NULL/zero. Care to do a couple of patches? cheers _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
