[PATCH 5.6 088/126] tools/bootconfig: Fix apply_xbc() to return zero on success

From: Greg Kroah-Hartman
Date: Tue May 26 2020 - 15:17:47 EST

[ Upstream commit 9d82ccda2bc5c148060543d249d54f8703741bb4 ]

The return of apply_xbc() returns the result of the last write() call, which
is not what is expected. It should only return zero on success.
