fd3c025314 drm/omap: call drm_put_dev directly in ->remove
Again omap already sets the driver data pointer to the drm_device.

Also drop the driver unregister call, that should be (and already is)
done in the module unload hook.

57a24cf897 drm/rcar: call drm_put_dev directly in the ->remove hook
The magic dance drm_platform_exit does is actually a remnant of the
old legacy shadow attach support for platform devices. Modern modesetting
drm drivers shouldn't do this any more (and usb/pci devices actually don't
do this).

ee61c7303f drm: Don't reference objects in the flink name idr
There's no reason to keep a reference to objects in the name idr.  Each
handle to an object has a reference to the object and just before we
destroy the last handle we take the object out of the name idr.  Thus,
if an object is in the name idr, there's at least one reference to the
object.

Or to put it another way, the name idr reference will never keep the
object alive.  It just looks like it, which is confusing.

520edd139a drm: do not steal the display if we have a master
Sometimes we want to disable all the screens on a system, because that
will allow the graphics card to be put into low-power states. The
problem is that, for example, while all screens are disabled, if we
get a hotplug interrupt, fbcon will decide to set a mode instead of
keeping everything disabled, which will remove us from our low power
states.

Let's assume that if there's a DRM master, it will be able to do
whatever is appropriate when we get the hotplug.

This problem can be reproduced by the runtime PM test program from
intel-gpu-tools: we disable all the screens so the graphics device can
be put into D3, then something triggers a hotplug interrupt, fbcon
sets a mode and breaks our test suite. The problem can be reproduced
more easily by the "i2c" subtest.

Other approaches considered for the problem:
    - Return "false" if "bound == 0" and the caller of
      drm_fb_helper_is_bound is a hotplug handler. This would break
      the case where the machine boots with no outputs connected, then
      the user plugs a monitor.
    - Add a new IOCTL to force fbcon to not set modes. This would keep
      all the current applications behaving the same, but adding a new
      IOCTL is not always the greatest idea.
    - Return false only if "dev->primary->master && bound == 0". This
      was my first implementation, but Chris suggested we should do
      the check irrespective of the "bound" variable.

Thanks to Daniel Vetter for the investigation, ideas and the
implementation of the hotplug alternative.

v2: - Do the check first, irrespective of "bound".

fffb906532 drm: Don't split up debug output
Otherwise we risk that the 2nd part of the line ends up on a line of
it's own, which means a kernel dmesg line without a log level. This
then upsets the dmesg checker in piglit.

Only really happens in some of the truly nasty igt testcases which
race cache dropping (through debugfs) with other gem operations.

45c2aff645 netfilter: nfnetlink_log: unset nf_loggers for netns when unloading module
Steven Rostedt and Arnaldo Carvalho de Melo reported a panic
when access the files /proc/sys/net/netfilter/nf_log/*.

This problem will occur when we do:

 echo nfnetlink_log > /proc/sys/net/netfilter/nf_log/any_file
 rmmod nfnetlink_log

and then access the files.

Since the nf_loggers of netns hasn't been unset, it will point
to the memory that has been freed.

This bug is introduced by commit 9368a53c ("netfilter: nfnetlink_log:
add net namespace support for nfnetlink_log").

b84caae486 qlcnic: Fix usage of netif_tx_{wake, stop} api during link change.
o Driver was using netif_tx_{stop,wake}_all_queues() api
  during link change event. Remove these api calls to
  manage queue start/stop event, as core networking stack
  will manage this based on netif_carrier_{on,off} call.
  These API's were modified as part of commit id
  012ec81223 ("qlcnic: Multi Tx
  queue support for 82xx Series adapter.")

fb5f1834c3 usb: ohci-at91: fix irq and iomem resource retrieval
When using dt resources retrieval (interrupts and reg properties) there is
no predefined order for these resources in the platform dev resources
table.

Retrieve resources using platform_get_resource and platform_get_irq
functions instead of direct resource table entries to avoid resource type
mismatch.

53385d2d1d neigh: Netlink notification for administrative NUD state change
The neighbour code sends up an RTM_NEWNEIGH netlink notification if
the NUD state of a neighbour cache entry is changed by a timer (e.g.
from REACHABLE to STALE), even if the lladdr of the entry has not
changed.

But an administrative change to the the NUD state of a neighbour cache
entry that does not change the lladdr (e.g. via "ip -4 neigh change
...  nud ...") does not trigger a netlink notification.  This means
that netlink listeners will not hear about administrative NUD state
changes such as from a resolved state to PERMANENT.

This patch changes the neighbor code to generate an RTM_NEWNEIGH
message when the NUD state of an entry is changed administratively.

Some of the callback functions that upload the firmware in the comedi
drivers return a positive value indicating the number of bytes sent

0283f7a100 staging: comedi: 8255_pci: fix for newer PCI-DIO48H
At some point, Measurement Computing / ComputerBoards redesigned the
PCI-DIO48H to use a PLX PCI interface chip instead of an AMCC chip.
This meant they had to put their hardware registers in the PCI BAR 2
region instead of PCI BAR 1.  Unfortunately, they kept the same PCI
device ID for the new design.  This means the driver recognizes the
newer cards, but doesn't work (and is likely to screw up the local
configuration registers of the PLX chip) because it's using the wrong
region.

Since  the PCI subvendor and subdevice IDs were both zero on the old
design, but are the same as the vendor and device on the new design, we
can tell the old design and new design apart easily enough.  Split the
existing entry for the PCI-DIO48H in `pci_8255_boards[]` into two new
entries, referenced by different entries in the PCI device ID table
`pci_8255_pci_table[]`.  Use the same board name for both entries.

27dc779835 Third set of fixes for IIO in the 3.13 cycle.
* Fix for a bug in the new cm36651 driver where it told the IIO driver it
   was providing a decimal part, but then didn't.  Now it correctly tells the
   IIO core that it is only providing an integer value.  This prevents random
   incorrect values being output on a sysfs read.
 
 * 3 fixes where drivers were miss specifying the endianness of their channels
   as output through the buffer interface.  These were discovered whilst
   removing the terrible IIO_ST macro once and for all.  The result is that
   userspace may be informed that the buffer elements are being output as
   little endian (on little endian platforms) when infact they are big endian.
   Thus userspace will handle them incorrectly.  This incorrect buffer
   element specification is provided as sysfs attributes under
   iio:deviceN/scan_elements.

3425c0f7ac iio:imu:adis16400 fix pressure channel scan type
A single channel in this driver was using the IIO_ST macro.
This does not provide a parameter for setting the endianness of
the channel.  Thus this channel will have been reported as whatever
is the native endianness of the cpu rather than big endian. This
means it would be incorrect on little endian platforms.

c5fe7a41ad staging:iio:mag:hmc5843 fix incorrect endianness of channel as a result of missuse of the IIO_ST macro.
This driver sets the shift value equal to IIO_BE (or 1) rather than setting
that to 0 and specificying the endianness.  This means the channel type is
missreported as
[be|le]:u16/16>>1 where the be|le is dependent on the cpu native endianness,
rather than
be:u16/16>>0 resulting in any userspace code using this information, miss
converting the channel and generating thoroughly trashed data.
