[netdrvr] atl1e: Don't take the mdio_lock in atl1e_probe
Lockdep warns about the mdio_lock taken with interrupts enabled then later
taken from interrupt context. Initially, I considered changing these
to spin_lock_irq/spin_unlock_irq, but then I looked at atl1e_phy_init()
and saw that it calls msleep(). Sleeping while holding a spinlock is
not allowed either.
In the probe path, we haven't registered the interrupt handler, so
it can't poke at this card yet. It's before we call register_netdev(),
so I don't think any other threads can reach this card either. If I'm
right, we don't need a spinlock at all.
