[PATCH 04/32] net: phy: micrel: drop useless assignment of dummy read

[Ahmad Fatoum]

The result of the PHY read is never used and the comment suggests this
is intentional. Still static analysis warns about this, so remove the
variable assignment and leave the read. We cast it to (void) to avoid
possible future __must_check warnings.
