There was NVMEM support added to of_get_mac_address, so it could now
return ERR_PTR encoded error values, so we need to adjust all current
users of of_get_mac_address to this new fact.
While at it, remove superfluous is_valid_ether_addr as the MAC address
returned from of_get_mac_address is always valid and checked by
is_valid_ether_addr anyway.

Some drivers were calling the skb_tx_timestamp() function only when

hardware timestamps, the drivers need to be modified to unconditionally
call skb_tx_timestamp().

The driver uses a private lock for synchronization of the xmit function and
the xmit completion handler, but since the NETIF_F_LLTX flag is not set,
the xmit function is also called with the xmit_lock held.
On the other hand the completion handler uses the reverse locking order by
first taking the private lock and (in case that the tx queue had been
stopped) then the xmit_lock.
Improve the locking by removing the private lock and using only the
xmit_lock for synchronization instead.

There are a couple bugs with the error handling in this function.
1) If we can't allocate "rx_ring->rx_skbuff" then we should call
dma_free_coherent() but we don't.
2) free_rx_ring() frees "rx_ring->rx_skbuff_dma" and "rx_ring->rx_skbuff"
so calling it in a loop causes a double free.
Also it was a bit confusing how we sometimes freed things before doing
the goto. I've cleaned it up so it does error handling in normal kernel
style.

Here's the set of driver core patches for 3.19-rc1.
They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes, just
removing a line in a structure.
Other than that, a few minor driver core and debugfs changes. There are
some ath9k patches coming in through this tree that have been acked by
the wireless maintainers as they relied on the debugfs changes.
