Subject: [PATCH 3/5] pinctrl: mvebu: Delete an unnecessary return statement in
 mvebu_pinconf_group_dbg_show()

The script "checkpatch.pl" pointed information out like the following.

WARNING: void function return statements are not generally useful

Thus remove such a statement in the affected function.
