That should be ok. The driver will only use valid register offsets in indirect mode during run time, so register 0x78 should point to a valid register. If indirect mode is never used by the driver, it will point to zero with this patch. So register 0x78 will be valid (or zero) in the kexec'ed kernel. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
