Subject: [PATCH net] stmmac: fix setting of driver data in stmmac_dvr_probe

Commit 803f8fc46274b ("stmmac: move driver data setting into
stmmac_dvr_probe") mistakenly set priv and not priv->dev as
driver data. This meant that the remove, resume and suspend
callbacks that fetched and tried to use this data would most
likely explode. Fix the issue by using the correct variable.

Hi,

I have no idea why I didn't notice (or anyone else for that
matter) this issue before now. Looking at 803f8fc46274b
it's pretty obvious and I should have spotted the mistake
when I sent the orignal patch. Anyway it's good to get this
fixed before 4.2 is released.

This should not conflict with any of the patches I sent for
net-next, btw.
