To make the attach a bit cleaner, factor the dma buffer allocation
out of attach_pci() into a new function.

The local variable 'resourceStart' is only used in the ioremap()
to hold the PCI bar 0 base address. Just use the pci_resource_start()
directly in the ioremap().
Also, instead of assuming the resource size for the ioremap, use
pci_resource_len() to get the actual size.
Remove the kernel noise when the ioremap fails and change the error
code from -ENODEV to -ENOMEM.

This variable is only used as a flag to indicate that the pci device
has been enabled and needs to be disabled in the detach. Use the
comedi_device 'iobase' for this and remove the private data variable.

The 'result' variable is only used to check the return from
comedi_pci_enable(). Just reuse the 'ret' variable.
Also, remove the kernel noise and use the error code from
comedi_pci_enable() instead of returning -ENODEV.

Convert this PCI driver to use the comedi PCI auto config attach
mechanism by adding an 'attach_pci' callback function. Since the
driver does not require any external configuration options, and
the legacy 'attach' callback is not optional, remove it.

Add subdevice 1 as an analog input (AI) subdevice. It currently only
supports basic, software-triggered acquisitions.
This is mostly the work of Fred Brooks (MODULE_AUTHOR), but he based his
update on an older version of the driver. I applied the relevant
changes with a few tweaks: adding an explicit `udelay(1)` in a timeout
loop, replacing binary constants with hex, renaming functions, replacing
`printk()` calls, removing exported symbols, removing (very) incomplete
comedi "command" support, and making some coding-style changes.

With the introduction of output entities, managers will now connect to outputs.
Use the helper op for managers named get_device. This will abstract away the
information on how to get the device from an overlay manager.
Using the helper function will reduce the number of pointer dereferences a user
of OMAPDSS needs to do and reduce risk of a NULL dereference.

Fifth round of new drivers and device support for the IIO
subsystem in the 3.7 cycle.
Here we have a mixed bag of new stuff, minor fixes and
more major fixes for drivers added earlier in this cycle.
1) A number of fixes for the HID sensors code added in previous
pull request. Typical stuff that has become apparent as more eyes
have looked at the code post merging. Similar case for the ad5755 dac.
2) Cleanups of error handing in inkern.c - again typical stuff to see
as code comes into heavier use and people notice the naughty short
cuts that snuck in originally and kindly fix them.
3) A series from Lars that removes some incorrect error handling
from the remove functions of a number of drivers. These have been
there for a very long time hence I'm not pushing these out for the
3.6 cycle.
4) Support for more parts in the ad7780 driver.
5) A driver for the adcs on the lp8788 power management unit
6) A client driver for IIO to allow it's ADCs to be used for
battery status measurement. Note this driver has some dependencies
on some utility functions added to IIO in this series, hence it is
coming via this tree rather than Anton's.
7) A null pointer dereference bug in the 'fake' driver. I'm not
doing this as a fix for the 3.6 cycle because it only effects
'fake' hardware and that code is typically only used by people
investigating how IIO works as part of writing new drivers. Hence
it's hardly a critical fix.

In dgrp_receive() there is:
desclen = ((plen - 12) > MAX_DESC_LEN) ? MAX_DESC_LEN :
plen - 12;
strncpy(nd->nd_ps_desc, b + 12, desclen);
However, it's possible for plen to be <= 12 here so we'd be passing a
negative number into the strncpy(). Fix this to not make the strncpy
call and report an error if desclen is <= 0

Manual backmerge of -rc7 to resolve a silent conflict leading to
compile failure in drivers/gpu/drm/i915/intel_hdmi.c.
This is due to the bugfix in -rc7:
commit b98b60167279df3acac9422c3c9820d9ebbcf9fb
Author: Wang Xingchao <xingchao.wang@intel.com>
Date: Thu Sep 13 07:43:22 2012 +0800
drm/i915: HDMI - Clear Audio Enable bit for Hot Plug
Since this code moved around a lot in -next git put that snippet at
the wrong spot. I've tried to fix this by making the conflict explicit
by merging a version for next with:
commit 3cce574f0190dd149472059fb69267cf83d290f9
Author: Wang Xingchao <xingchao.wang@intel.com>
Date: Thu Sep 13 11:19:00 2012 +0800
drm/i915: HDMI - Clear Audio Enable bit for Hot Plug unconditionally
But that failed to solve the entire problem. To avoid pushing out
further -nightly branch to our QA where this is broken, do the
backmerge and manually add the stuff git adds to -next from the patch
in -fixes.
Note that this doesn't show up in git's merge diff (and hence is also
not handled by git rerere), which adds to the reasons why I'd like to
fix this with a verbose backmerge. The git merge diff only shows a
bunch of trivial conflicts of the "code changed in lines next to each
another" kind.

If the config contains CONFIG_IIO_BUFFER=y and CONFIG_IIO_SIMPLE_DUMMY_BUFFER=n
iio_simple_dummy_configure_buffer() is stubbed out and iio_buffer_register() is
not. As a result we try to register a buffer which has not been configured.
This will causes a NULL pointer deref in iio_buffer_register. To solve this
issue move the iio_buffer_register() call to iio_simple_dummy_configure_buffer(),
so it will only be called if iio_simple_dummy_configure_buffer() has been called.

In the Linux device driver model the remove callback is not allowed to fail and
the device will be removed regardless of the return value of the remove
callback. So if we abort in the remove function and do not free all resources we
will create a resource leak. Also all kinds of undefined behaviour are expected
to happen since the IIO device is still there while its parent is already gone.
The errors which the driver tries to handle in the remove function are
non-critical, so we can just ignore them and continue to free all resources and
remove the IIO device.
