Subject[PATCH 4.6 47/96] pinctrl: imx: Do not treat a PIN without MUX register as an error
Date
4.6-stable review patch.  If anyone has any objections, please let me know.

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

From: Alexander Shiyan <shc_work@mail.ru>

commit ba562d5e54fd3136bfea0457add3675850247774 upstream.

Some PINs do not have a MUX register, it is not an error.
It is necessary to allow the continuation of the PINs configuration,
otherwise the whole PIN-group will be configured incorrectly.
