In lanphy_read_page_reg, calling __phy_read() might return a negative
error code. Use 'int' to check the negative error code.

Hi Wan
As far as the code goes, this looks good.
Please could you add a Fixes: tag, to indicate where the problem was
introduced. Please also read the netdev FAQ, so you can correctly set
the patch subject. This should be against the net tree, since it is a
fix.
Thanks
Andrew

Hi,
Please correct the spelling error of "incorrect" in the subject line.
Thanks.
