From 8e3ecc87695f4a7e9e217ebd55ca6a39b6a451b8 Mon Sep 17 00:00:00 2001 From: Cyril Roelandt Date: Fri, 4 Apr 2014 00:05:21 +0200 Subject: fs: cifs: remove unused variable. In SMB2_set_compression(), the "res_key" variable is only initialized to NULL and later kfreed. It is therefore useless and should be removed.
