PHY: remove rwsem use from phy core
The subsystem rwsem is not used by the driver core at all, so the use of it in the phy code doesn't make any sense. They might possibly want to use a local lock, but I am unsure about that. Cc: netdev <netdev@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
