Re: [PATCH] sky2: avoid using uninitialized variable

In my experience if phy reads once successfully, it is going
to read every time. If there is a problem it only happens on
the first access (powered off, bad timing, etc).

It also happens when the PHY can't get a response for a certain
register, for whatever reason, before internal hw timeouts trigger.

Please, check all MII accesses.  That's what I do in every driver
I've written.
