Subject: Not all i.MX6 devices have a pinctrl property in their device nodes.
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=f99b17ada10cba841a6da149bf8d5668e0c946ce;p=openbsd

Not all i.MX6 devices have a pinctrl property in their device nodes.
In that case, soft fail and return instead of allocating buffer with
a bogus size.
