Socket must be held while under the protection of the l2tp lock; there
is no guarantee that sk remains valid after the read_unlock_bh() call.
Same issue for l2tp_ip and l2tp_ip6.

Socket flags aren't updated atomically, so the socket must be locked
while reading the SOCK_ZAPPED flag.
This issue exists for both l2tp_ip and l2tp_ip6. For IPv6, this patch
also brings error handling for __ip6_datagram_connect() failures.

The ER records are printed without explicit log level presuming line
continuation until "\n". After the commit 4bcc595ccd8 (printk:
reinstate KERN_CONT for printing continuation lines), the ER records are
printed a character per line.
Adding KERN_CONT to appropriate printk statements restores the printout
behavior.

Execution 'ethtool -S' on fec device that is down causes OOPS on Vybrid
board:
Unhandled fault: external abort on non-linefetch (0x1008) at 0xe0898200
pgd = ddecc000
[e0898200] *pgd=9e406811, *pte=400d1653, *ppte=400d1453
Internal error: : 1008 [#1] SMP ARM
...
Reason of OOPS is that fec_enet_get_ethtool_stats() accesses fec
registers while IPG clock is stopped by PM.
Fix that by caching statistics in fec_enet_private. Cache is initialized
at device probe time, and updated at statistics request time if device
is up, and also just before turning device off on down path.
Additional locking is not needed, since cached statistics is accessed
either before device is registered, or under rtnl_lock().

The DT binding for tildc is not consistent with the driver code: there
are two options - 'max-width' and 'max-pixelclock' specified in the
documentation which are parsed as 'ti,max-width' and
'ti,max-pixelclock' respectively.
Make the driver code consistent with the binding.

Adds drm bride support for attaching drm bridge drivers to tilcdc. The
decision whether a video port leads to an external encoder or bridge
is made simply based on remote device's compatible string. The code

Add very basic ti-tfp410 DVI transmitter driver. The only feature
separating this from a completely dummy bridge is the EDID read
support trough DDC I2C. Even that functionality should be in a
separate generic connector driver. However, because of missing DRM
infrastructure support the connector is implemented within the bridge
driver. Some tfp410 HW specific features may be added later if needed,
because there is a set of registers behind i2c if it is connected.
This implementation is tested against my new tilcdc bridge support
and it works with BeagleBone DVI-D Cape Rev A3. A DT binding document
is also updated.

Recover from sync lost error flood by resetting the LCDC instead of
turning off the SYNC_LOST error IRQ. When LCDC starves on limited
memory bandwidth it may sometimes result an error situation when the
picture may have shifted couple of pixels to right and SYNC_LOST
interrupt is generated on every frame. LCDC main reset recovers from
this situation and causes a brief blanking on the screen.

====================
net: fix fixed-link phydev leaks
This series fixes failures to deregister and free fixed-link phydevs
that have been registered using the of_phy_register_fixed_link()
interface.
All but two drivers currently fail to do this and this series fixes most
of them with the exception of a staging driver and the stmmac drivers
which will be fixed by follow-on patches.
Included are also a couple of fixes for related of-node leaks.
Note that all patches except the of_mdio one have been compile-tested
only.
Also note that the series is against net due to dependencies not yet in
net-next.
