linux-next: build warning after merge of the driver-core tree

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi all,

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

fs/ubifs/debug.c: In function 'dbg_debugfs_init_fs':
fs/ubifs/debug.c:2812:6: warning: unused variable 'err' [-Wunused-variable]
  int err, n;
      ^~~

Introduced by commit

  702d6a834b49 ("ubifs: no need to check return value of debugfs_create functions")

Cheers,
Stephen Rothwell
