phy_addr_sel_strap is currently bool.

If this is to be changed, it should be set
true or false.

My preference would be:

chip->phy_addr_sel_strap = (reg != 0 && reg != 0xffff);

But perhaps its bool type should be converted
to int as this phy_addr_sel_strap is used as
int several times.


Hi Joe

I had not noticed that phy_addr_sel_strap is bool. I agree that is
misleading. Your suggestion is perhaps a bit "magic", but on the other
hand the magic is explained well in the comment above.

If there are no disagreements, I can do a v2 with that.

And thanks for teaching me about "git grep"!

Cheers
Egil
