Subject: slow-work: use get_ref wrapper instead of directly calling get_ref
X-Git-Tag: v2.6.32.18~11
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2891de04359b824964e9ee9c87fbea2637e934fd;p=karo-tx-linux.git

slow-work: use get_ref wrapper instead of directly calling get_ref

commit 88be12c440cfa2fa3f5be83507360aac9ea1c54e upstream.

Otherwise we can get an oops if the user has no get_ref/put_ref
requirement.
