Smatch complains because we dereference "ses->server" without checking some lines earlier inside the call to get_next_mid(ses->server). fs/cifs/cifssmb.c:4921 CIFSGetDFSRefer() warn: variable dereferenced before check 'ses->server' (see line 4899) There is only one caller for this function get_dfs_path() and it always passes a non-null "ses->server" pointer so this NULL check can be removed.
