Fix <linux/kmsg_dump.h> when CONFIG_PRINTK is not enabled:
include/linux/kmsg_dump.h:56: error: 'EINVAL' undeclared (first use in this function)
include/linux/kmsg_dump.h:61: error: 'EINVAL' undeclared (first use in this function)
Looks like commit 595dd3d8bf ("kmsg_dump: fix build for
CONFIG_PRINTK=n") uses EINVAL without having the needed header file(s),
but I'm sure that I build tested that patch also. oh well.
