On resume the slave controller is reinitialized. The tegra i2c master
controller disables the clock at the end of the initialiation, propably
to save some power, and enables it again on each transfer. We don't
do this yet and also forgot to enable the clock on resume. Fix this
copy-paste error by not disabling the clock after initialization.
This didn't striked us yet because suspend/resume hasn't landed in mainline
yet, but will soon.

This buffer is used to cache the values that are written to the

to the channels using the (*insn_write) callback. The async command
writes are not cached. The buffer is also being kzalloc'ed during
the attach of the driver to a size much larger that required.
Rename the CamelCase buffer and change it to an array in the private

Modify the analog output urb callback so it updates the cached values
with those used for the asynchronous command to allow readback after
the command completes.
The sanity check of the index to dac_commands[] (i.e. the 'chan' being
written) is not needed. The chanlist_len will always be less than the
number of channels.

The COMEDI_NI_ATMIO configuration option causes the "ni_atmio" module to
be built, which handles various National Instruments ISA-PNP data
acquisition cards. The configuration option currently depends on
ISAPNP.
The "ni_atmio" module is a "legacy" comedi driver with no
auto-configuration support and it doesn't register as a PNP card driver.
The only difference in initialization from the other comedi ISA card
drivers is that it will use the ISA-PNP functions to find, attach and
activate the card if no I/O base address has been specified by the user
in the COMEDI_DEVCONFIG ioctl.
The module compiles fine without the ISAPNP configuration option as the
<linux/isapnp.h> and <linux/pnp.h> headers provide dummy inline
functions if the ISAPNP and PNP options, respectively, are not enabled.
Remove the dependancy on the ISAPNP option since the module builds
without it and can be used without it.
(There is a very slim chance that comedi will support proper ISA PNP
drivers one day, in which case the ni_atmio driver could be converted to
use this support and not support manual configuration. However, not all
the PnP IDs of boards supported by this driver are currently known to
us.)

Commit 8c5bd7a (ACPI / video / i915: No ACPI backlight if firmware
expects Windows 8) introduced for this purpose essentially prevented
the ACPI backlight support from being used if the BIOS had been told
that the OS was compatible with Windows 8 and the i915 driver was
loaded, in which case the backlight would always be handled by i915.
Unfortunately, however, that turned out to cause problems with
backlight to appear on multiple systems with symptoms indicating that
i915 was unable to control the backlight on those systems as
expected.
For this reason, revert commit 8c5bd7a, but leave the function
acpi_video_backlight_quirks() introduced by it, because another
commit on top of it uses that function.

ahci_imx makes use of regmap but the dependency wasn't specified in
Kconfig leading build failures if CONFIG_AHCI_IMX is enabled but

tracing: Remove locking trace_types_lock from tracing_reset_all_online_cpus()
Commit a82274151af "tracing: Protect ftrace_trace_arrays list in trace_events.c"
added taking the trace_types_lock mutex in trace_events.c as there were
several locations that needed it for protection. Unfortunately, it also
encapsulated a call to tracing_reset_all_online_cpus() which also takes
the trace_types_lock, causing a deadlock.
This happens when a module has tracepoints and has been traced. When the
module is removed, the trace events module notifier will grab the
trace_types_lock, do a bunch of clean ups, and also clears the buffer
by calling tracing_reset_all_online_cpus. This doesn't happen often
which explains why it wasn't caught right away.
Commit a82274151af was marked for stable, which means this must be
sent to stable too.

Brown-paper-bag pull request here. The snb rc6 fix from the last pull

mfd: max8925: fix dt code for backlight
The device-tree enablement for max8925 has several problems, but besides
the bindings being wrong (and not having seen review) there's also some
bad coding practices on how to fill in the platform_data from device tree.
I came across this since it causes a warning when compiling
mmp2_defconfig, and instead of doing the minimal fix to silence the
warning, I restructured the code a bit.
This silences the warning:
drivers/video/backlight/max8925_bl.c: In function 'max8925_backlight_probe':
drivers/video/backlight/max8925_bl.c:177:3: warning: statement with no effect [-Wunused-value]
Note that the bindings themselves need to be revisited too, but that will
affect more than just the backlight driver and is best done separately;
this just fixes the bad code for the backlight driver.

staging: New driver: Xillybus generic interface for FPGA
This is the driver for Xillybus, which is a general-purpose interface for
data communication with FPGAs (programmable logic). Please refer to the
README included in this patch for a detailed explanation.
It was previously submitted for misc-devices, but it appears like noone's
willing to review the code (which I can understand, given its magnitude).
Hence submitted as a staging driver.

Staging: olpc_dcon: change to msleep to usleep_range
The resolution of msleep is related to HZ, so with HZ set to
100 any msleep of less then 10ms will become ~10ms. This is
not what we want. Use usleep_range to get more control of
what is happening here.
staging: dwc2: Don't touch the dma_mask when dma is disabled
There was some code that cleared the dma_mask when dma was disabled in
the driver. Given that clearing the mask doesn't actually tell the usb
core we're not using dma, and a previous commit explicitely sets the
hcd->self.uses_dma value, it seems these values are unneeded and can
only potentially cause problems (when reloading a module, for example).

drm/imx: kill firstopen callback
This thing seems to do some kind of delayed setup. Really, real kms
drivers shouldn't do that at all. Either stuff needs to be dynamically
hotplugged or the driver setup sequence needs to be fixed.
This patch here just moves the setup at the very end of the driver
load callback, with the locking adjusted accordingly.
v2: Also move the corresponding put from ->lastclose to ->unload.
imx-drm: imx-tve: Remove unneeded check for platform_get_resource()
As devm_ioremap_resource() is used on probe, there is no need to explicitly
check the return value from platform_get_resource(), as this is something that
devm_ioremap_resource() takes care by itself.
