I have pushed the following fix which should cure this:

--------------------
stmmac: fix stmmac_resume removing not yet used shutdown flag

The commit to convert to use the dev_pm_ops struct
introduces a bug. The shutdown flag is not yet used
because the hibernation on memory is done by using
the freeze callback.
Thanks to Vlad for having reported it.
