I don't think you need to resend, but the Fixes tag format isn't
right.
1) Don't line wrap it. (Maybe checkpatch complains? Ignore checkpatch).
2) Put a space between the git hash and the '('.
3) No blank line between the Fixes and the Reported-by.

You may as well make wilc_debugfs_init() void since no one checks it.

Just check for NULL. If someone builds without debugfs enabled in their
.config, that's their choice. No need to print a warning.
