autofs-5.1.8 - add soucre parameter to module functions
From: Ian Kent <raven@themaw.net>
There's a unnecessarily complicated method used to pass the map source
to module read map and lookup mount functions. This also confuses
coverity which constantly complains about unmatched locking.
Just add a parameter to those functions to simplify it and elliminate
the coverity false positives not to mention slightly less overhead by
the lock removal.
Signed-off-by: Ian Kent <raven@themaw.net>
