commit bb475230b8e59a547ab66ac3b02572df21a580e9 upstream.
The *_get_optional_* functions weren't really optional so this patch
makes them really optional.
These *_get_optional_* functions will now return NULL instead of an error
if no matching reset phandle is found in the DT, and all the
reset_control_* functions now accept NULL rstc pointers.

Please apply to v4.9.y stable tree.
The original commit had a few upstream fixes:
bb6c7768385b reset: remove remaining WARN_ON() in <linux/reset.h>
1554bbd4ad40 reset: make device_reset_optional() really optional
62e24c5775ec reset: add exported __reset_control_get, return NULL if
optional
0ca10b60ceeb reset: fix optional reset_control_get stubs to return NULL
4891486fb2c8 reset: core: fix reset_control_put
We'll need to backport them to 4.9 as well if you backport this commit.
Hmm..I was able to fix an ethernet driver load issue by just backporting
this patch. Should I investigate backport of the other patches as well?
That patch will probably work on it's own, but if there are fixes for it
then they should be backported as well.
