Subject: [PATCH 4.14 46/55] reset: remove remaining WARN_ON() in <linux/reset.h>

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Masahiro Yamada <yamada.masahiro@...ionext.com>

commit bb6c7768385b200063a14d6615cc1246c3d00760 upstream.

Commit bb475230b8e5 ("reset: make optional functions really optional")
gave a new meaning to _get_optional variants.

The differentiation by WARN_ON() is not needed any more.  We already
have inconsistency about this; (devm_)reset_control_get_exclusive()
has WARN_ON() check, but of_reset_control_get_exclusive() does not.
