dab363f938 Staging patches for 3.19-rc1
Here's the big staging tree pull request for 3.19-rc1.
 
 We continued to delete more lines than were added, always a good thing,
 but not at a huge rate this release, only about 70k lines removed
 overall mostly from removing the horrid bcm driver.
 
 Lots of normal staging driver cleanups and fixes all over the place,
 well over a thousand of them, the shortlog shows all the horrid details.
 
 The "contentious" thing here is the movement of the Android binder code
 out of staging into the "real" part of the kernel.  This is code that
 has been stable for a few years now and is working as-is in the tens of
 millions of devices with no issues.  Yes, the code is horrid, and the
 userspace api leaves a lot to be desired, but it's not going to change
 due to legacy issues that we have no control over.  Because so many
 devices and companies rely on this, and the code is stable, might as
 well promote it out of staging.
 
 This was all discussed at the Linux Plumbers conference, and everyone
 participating agreed that this was the best way forward.
 
 There is work happening to replace the binder code with something new
 that is happening right now, but I don't expect to see the results of
 that work for another year at the earliest.  If that ever happens, and
 Android switches over to it, I'll gladly remove this version.
 
 As for maintainers, I'll be glad to maintain this code, I've been doing
 it for the past few years with no problems.  I'll send a MAINTAINERS
 entry for it before 3.19-final is out, still need to talk to the Google
 developers about if they are willing to help with it or not, last I
 checked they were, which was good.
 
 All of these patches have been in linux-next for a while with no
 reported issues.

e6b5be2be4 Driver core patches for 3.19-rc1
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.
 
 Everything has been in linux-next for a while.

6da314122d ARM: SoC DT updates for 3.19
The DT branch adds a lot of new stuff for additional SoC and board
 support. The branch is the largest one and contains 513 out of the
 total 972 non-merge arm-soc changesets for 3.19.
 
 Most of the changes are about enabling additional on-chip devices for
 existing machines, but there are also an unusual number of new SoC
 types being added this time:
 
 * AMLogic Meson8
 * ARM Realview in DT mode
 * Allwinner A80
 * Broadcom BCM47081
 * Broadcom Cygnus
 * Freescale LS1021A
 * Freescale Vybrid 500 series
 * Mediatek MT6592, MT8127, MT8135
 * STMicroelectronics STiH410
 * Samsung Exynos4415
 
 The level of support for the above differs widely, some are just
 stubs with nothing more than CPU, memory and a UART, but others
 are fairly complete. As usual, these get extended over time.
 
 There are also many new boards getting added, this is the
 list of model strings that are showing up in new dts files:
 
 * ARM RealView PB1176
 * Altera SOCFPGA Arria 10
 * Asus RT-N18U (BCM47081)
 * Buffalo WZR-1750DHP (BCM4708)
 * Buffalo WZR-600DHP2 (BCM47081)
 * Cygnus Enterprise Phone (BCM911360_ENTPHN)
 * D-Link DIR-665
 * Google Spring
 * IGEP COM MODULE Rev. G (TI OMAP AM/DM37x)
 * IGEPv2 Rev. F (TI OMAP AM/DM37x)
 * LS1021A QDS Board
 * LS1021A TWR Board
 * LeMaker Banana Pi
 * MarsBoard RK3066
 * MediaTek MT8127 Moose Board
 * MediaTek MT8135 evaluation board
 * Mele M3
 * Merrii A80 Optimus Board
 * Netgear R6300 V2 (BCM4708)
 * Nomadik STN8815NHK
 * NovaTech OrionLXm

 * Synology DS414
 * TBS2910 Matrix ARM mini PC
 * TI AM5728 BeagleBoard-X15
 * Toradex Colibri VF50 on Colibri Evaluation Board
 * Zynq ZYBO Development Board
 
 Other notable changes include:
 
 * exynos: cleanup of existing dts files
 * mvebu: improved pinctrl support for Armada 370/XP
 * nomadik: restructuring dts files
 * omap: added CAN bus support
 * shmobile: added clock support for some SoCs

e10554738c staging:iio:ade7758: Fix NULL pointer deref when enabling buffer
In older versions of the IIO framework it was possible to pass a completely
different set of channels to iio_buffer_register() as the one that is
assigned to the IIO device. Commit 959d2952d1 ("staging:iio: make
iio_sw_buffer_preenable much more general.") introduced a restriction that
requires that the set of channels that is passed to iio_buffer_register() is
a subset of the channels assigned to the IIO device as the IIO core will use
the list of channels that is assigned to the device to lookup a channel by
scan index in iio_compute_scan_bytes(). If it can not find the channel the
function will crash. This patch fixes the issue by making sure that the same
set of channels is assigned to the IIO device and passed to
iio_buffer_register().

Note that we need to remove the IIO_CHAN_INFO_RAW and IIO_CHAN_INFO_SCALE
info attributes from the channels since we don't actually want those to be
registered.

Fixes the following crash:
	Unable to handle kernel NULL pointer dereference at virtual address 00000016
	pgd = d2094000

4a53d3afa0 staging:iio:ad5933: Fix NULL pointer deref when enabling buffer
In older versions of the IIO framework it was possible to pass a
completely different set of channels to iio_buffer_register() as the one
that is assigned to the IIO device. Commit 959d2952d1 ("staging:iio: make
iio_sw_buffer_preenable much more general.") introduced a restriction that
requires that the set of channels that is passed to iio_buffer_register() is
a subset of the channels assigned to the IIO device as the IIO core will use
the list of channels that is assigned to the device to lookup a channel by
scan index in iio_compute_scan_bytes(). If it can not find the channel the
function will crash. This patch fixes the issue by making sure that the same
set of channels is assigned to the IIO device and passed to
iio_buffer_register().

Fixes the follow NULL pointer derefernce kernel crash:

e3fe42b149 Staging: iio: adc: Refine delay computation
As per comment in function ad7280_delay, conversion delay may take up
to 250us. We cannot rely on msleep for this because it may sleep longer
than intended time for values less than 20ms, so use usleep_range instead.

Problem detected using checkpatch.pl.
