These patches look good to me, but I agree with Andreas's remark for "realtek:
simplify log messages in rtl83xx_mdio_probe". If you don't get any comments on
moving cond_resched() to the loops, can you do a respin?

I've already picked patches 1, 3, and 4. So you would only need to do the two
remaining ones.

Best,
