This buffer is used to cache the values that are written to the
analog output channels. Currently it only caches the single writes
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
data of the correct size to cache the analog output channel values.
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.
Also, fix the dev_err() message so it uses the proper device pointer.

All the unlink helpers simply call usb_kill_urb() to cancel any pending

extra sanity check is not required.
The unlink helpers will always return success so just make them void

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.)

The COMEDI_NI_ATMIO16D configuration option causes the "ni_atmio16d"
module to be built, which handles the National Instruments AT-MIO-16 and
AT-MIO-16D cards. The configuration option currently depends on ISAPNP,
but the module doesn't use any ISAPNP functions and the cards are legacy
ISA cards with base I/O port, IRQ and DMA channel configured by jumpers.
(The driver doesn't use DMA though.)
Remove the ISADNP dependancy from COMEDI_NI_ATMIO16D and fix up the help
text - the card names are missing a dash and they're not ISA-PNP.

Pull qxl drm fixes from Dave Airlie:
"Okay as I warned, the qxl driver was running a bit free and loose with
its ttm object reservations and the new lockdep enabled reservation
tracking shone a bright light into it, it also with the new
reservations mutexes hits a possible deadlock during boot.
The first patch is a real fix to render the console correctly as the
driver used to just drop irq renderering as too hard, this also fixes
a sleeping while atomic warning.
The other two patches are the big ugly ones that redo how the driver
allocates objects and reserves them and makes things all work
properly, I've tested this in a VM, and compared to the current code
which hits a lockdep warning and the sleep while atomic warning before
failing.
So sorry this is coming in late, I should have tested qxl before
merging the mutex code, but I'd rather just fix qxl with this than
revert the reservations code at this point"
* 'qxl-fixes' of git://people.freedesktop.org/~airlied/linux:
qxl: convert qxl driver to proper use for reservations
qxl: allow creation of pre-pinned objects and use for releases.
drm/qxl: add delayed fb operations
- Revert of the ACPI video commit that I hoped would help fix
backlight problems related to Windows 8 compatibility on some
systems. Unfortunately, it turned out to cause problems to happen
too.
- Fix for two problems in intel_pstate, a possible failure to respond
to a load change on a quiet system and a possible failure to select
the highest available P-state on some systems. From Dirk Brandewie.
