Subject: linux-next: build warning after merge of the ext4 tree

Hi Theodore,

After merging the ext4 tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

fs/ext4/super.c: In function 'parse_options':
fs/ext4/super.c:1976:26: warning: unused variable 'grp_qf_name' [-Wunused-variable]
  char *p, *usr_qf_name, *grp_qf_name;
                          ^~~~~~~~~~~
fs/ext4/super.c:1976:12: warning: unused variable 'usr_qf_name' [-Wunused-variable]
  char *p, *usr_qf_name, *grp_qf_name;
            ^~~~~~~~~~~

Introduced by commit

  20cefcdc2040 ("ext4: fix use-after-free race in ext4_remount()'s error path")

# CONFIG_QUOTA is not set
