CIFS: Remove pointless variable assignment in cifs_dfs_do_automount()
In fs/cifs/cifs_dfs_ref.c::cifs_dfs_do_automount() we have this code: ... mnt = ERR_PTR(-EINVAL); if (IS_ERR(tlink)) { mnt = ERR_CAST(tlink); goto free_full_path; } ses = tlink_tcon(tlink)->ses; rc = get_dfs_path(xid, ses, full_path + 1, cifs_sb->local_nls, &num_referrals, &referrals, cifs_sb->mnt_cifs_flags & CIFS_MOUNT_MAP_SPECIAL_CHR); cifs_put_tlink(tlink); mnt = ERR_PTR(-ENOENT); ... The assignment of 'mnt = ERR_PTR(-EINVAL);' is completely pointless. If we take the 'if (IS_ERR(tlink))' branch we'll set 'mnt' again and we'll also do so if we do not take the branch. There is no way we'll ever use 'mnt' with the assigned 'ERR_PTR(-EINVAL)' value, so we may as well just remove the pointless assignment.
