Subject: kmsg_dump.h: fix build when CONFIG_PRINTK is disabled
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=ac5622418bbff9cd3dc607aa57dfb4f62a7f2043;p=openwrt%2Fstaging%2Fblogic.git

kmsg_dump.h: fix build when CONFIG_PRINTK is disabled

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 595dd3d8bf95 ("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.
