Take a reference on the sessions returned by l2tp_session_find_nth()
(and rename it l2tp_session_get_nth() to reflect this change), so that
caller is assured that the session isn't going to disappear while
processing it.
For procfs and debugfs handlers, the session is held in the .start()
callback and dropped in .show(). Given that pppol2tp_seq_session_show()
dereferences the associated PPPoL2TP socket and that
l2tp_dfs_seq_session_show() might call pppol2tp_show(), we also need to
call the session's .ref() callback to prevent the socket from going
away from under us.

During probe, the rcar_can driver prints:
rcar_can e6e80000.can: device registered (regs @ e08bc000, IRQ76)
The "regs" value is a virtual address, exposing internal information,
hence stop printing it. The (useful) physical address is already
printed as part of the device name.

Starting from commit 5de85b9d57ab ("PM / runtime: Re-init runtime PM
states at probe error and driver unbind") pm_runtime core now changes
device runtime_status back to after RPM_SUSPENDED after a probe defer.
Certain OMAP devices make use of "ti,no-idle-on-init" flag which causes
omap_device_enable to be called during the BUS_NOTIFY_ADD_DEVICE event
during probe, along with pm_runtime_set_active.
This call to pm_runtime_set_active typically will prevent a call to
pm_runtime_get in a driver probe function from re-enabling the
omap_device. However, in the case of a probe defer that happens before
the driver probe function is able to run, such as a missing pinctrl
states defer, pm_runtime_reinit will set the device as RPM_SUSPENDED and
then once driver probe is actually able to run, pm_runtime_get will see
the device as suspended and call through to the omap_device layer,
attempting to enable the already enabled omap_device and causing errors
like this:
omap-gpmc 50000000.gpmc: omap_device: omap_device_enable() called from
invalid state 1
omap-gpmc 50000000.gpmc: use pm_runtime_put_sync_suspend() in driver?
We can avoid this error by making sure the pm_runtime status of a device
matches the omap_device state before a probe attempt. By extending the
omap_device bus notifier to act on the BUS_NOTIFY_BIND_DRIVER event we
can check if a device is enabled in omap_device but with a pm_runtime
status of RPM_SUSPENDED and once again mark the device as RPM_ACTIVE to
avoid a second incorrect call to omap_device_enable.

error and driver unbind")

The HDMI TX controller support HPD and RXSENSE signaling from the PHY
via it's STAT0 PHY interface, but some vendor PHYs can manage these
signals independently from the controller, thus these STAT0 handling
should be moved to PHY specific operations and become optional.
The existing STAT0 HPD and RXSENSE handling code is refactored into
a supplementaty set of default PHY operations that are used automatically
when the platform glue doesn't provide its own operations.
