[PATCH v2 11/13] backports: prefix c-file / h-file auto backport with BPAUTO

Luis R. Rodriguez
2014-11-05T03:19:38Z

From: "Luis R. Rodriguez" <mcgrof@suse.com>

Things we backport are now prefixed with BACKPORT_, when we copy
over libraries with the c-files / h-files trick on the compat/Kconfig
trick we prefix these with BACKPORT_ already so in order to help
distinguish them use BACKPORT_BPAUTO_ for them and prevent a double
BACKPORT_ prefix.
