Subject: kbuild: Re-sync DTC flag logic with v4.17
X-Git-Tag: v2020.07-rc1~41^2~9^2~16
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e0d1a89a5baec862a71384f7ddeebdf9d9c4ec63;p=pandora-u-boot.git

kbuild: Re-sync DTC flag logic with v4.17

The way that we have been handling additional DTC warning flags hasn't
matched the way the Linux Kernel does.  Resync this logic with v4.17.
