[PATCH 3.18 13/27] Revert "bsg-lib: dont free job in bsg_prepare_job"

From: Greg Kroah-Hartman
Date: Thu Oct 19 2017 - 10:00:36 EST


3.18-stable review patch. If anyone has any objections, please let me know.

------------------

From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>

This reverts commit d9100405a20a71dd620843e0380e38fc50731108 which was
commit f507b54dccfd8000c517d740bc45f20c74532d18 upstream.

Ben reports:
That function doesn't exist here (it was introduced in 4.13).
Instead, this backport has modified bsg_create_job(), creating a
leak. Please revert this on the 3.18, 4.4 and 4.9 stable
branches.

So I'm dropping it from here.
