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. Found with the following semantic patch: <smpl> @@ identifier foo; identifier f; type T; @@ * f(...) { ... * T *foo = NULL; ... when forall when != foo * kfree(foo); ... } </smpl> Signed-off-by: Cyril Roelandt <tipecaml@gmail.com> Signed-off-by: Steve French <sfrench@us.ibm.com>
