[RFC PATCH 06/17] phy_driver: Add and use phy_driver_[un]register_multiple()

From: Kyle Moffett
Date: Thu Oct 20 2011 - 17:17:32 EST

Several of the PHY drivers are registering dozens of "phy_driver"
structures at load-time, with different IDs and variations on methods.
As a result, the error handling is exceptionally ugly.

The "marvell" driver already uses an array of "struct phy_driver" and
iterates over that to add the drivers, but even then its error handling
contains a bug (it will not unregister array item 0 on failure).

To resolve these problems, new functions phy_driver_register_multiple()
and phy_driver_unregister_multiple() are added which take an array and a
number of drivers and iterate over them internally.

All of the PHY driver files which register more than one "phy_driver"
are modified to use the new helpers. This is a sizable net removal of
about 260 lines of code.
