Merge tag 'iio-for-3.18a' of git://git./linux/kernel/git/jic23/iio into work-next

Jonathan writes:

1st round of new IIO drivers, functionality and cleanups for the 3.18 cycle.

Maintainer Updates

* Add 3 designated reviewers for IIO.  Lars, Peter and Hartmut have been
  actively reviewing a lot of patches for a while now so this reflects
  the status quo.  These three are probably the only reason I keep
  my head above the water!

New drivers and device support

* max5821 DAC
* Rockchip SARADC
* TI ADC128S052 ADC
* BMC150 Accelerometer
* exynos ADC driver gains support for s3c24xx and s3c64xx parts.
* kxcjk-1013 gainst range control and runtime PM support to drive
  down it's power usage.

Driver removals

* Drop ad5930, ad99850, ad9852, ad9910 and ad9951 drivers on the simple
  basis that they drivers just provided a register write function with
  no compliant user space ABI whatsoever.  Much better to drop them and
  start again for these in the fullness of time.

Core Enhancements

* Join together neighbouring elements in the demux units that feeds
  the binary interfaces.  This cuts down on the number of individual
  copies needed  when splitting out individual channels from the incoming
  channel scans.
* Other demux related cleanups such as using roundup instead of a local
  implementation.

Cleanups

* Drop an unnecessary double setting of the owner field in xilinx adc.
* Some more patches to use managed (devm) interfaces to cut down on
  complexity of removal code.
* adis16060 coding style fixlets.
* Fix some incorrect error returns in the Xilinx ADC driver.
* Coding style fixlets for various accelerometer drivers.
* Some sparse warning fixes to do with endianness and sign of variables.
* Fix an incorrect and entirely pointless use of sizeof on a dynamic pointer
  in hid-sensor-magn-3d by dropping the relevant code.

iio: adc: xilinx: Remove .owner field for driver

There is no need to init .owner field.

Based on the patch from Peter Griffin <peter.griffin@linaro.org>
"mmc: remove .owner field for drivers using module_platform_driver"

This patch removes the superflous .owner field for drivers which
use the module_platform_driver API, as this is overriden in
platform_driver_register anyway."

staging:iio: Remove ad5930/ad9850/ad9852/ad9910/ad9951 dummy drivers

All what these 'drivers' do is expose a single (non standard ABI) sysfs
attribute that when written to does a direct pass-through to spi_write(). This
is rather ugly and does not justify the existence of a driver as the same can
easily done by using the spidev interface.

The drivers will eventually be rewritten as proper IIO ABI compliant drivers
which do have the proper abstraction layers between userspace and the device.
But in the meantime these driver do not add any extra value and just clutter up
the staging area. So just remove them.

staging: dgnc: Remove unnecessary dgnc_Major_Control_Registered variable

The dgnc_Major_Control_Registered variable purpose was to act as a flag
to indicate if the character device has been successfully registered
into the kernel. This flag was later checked in the module cleanup
function to know if the character device needs to be deregistered.

However the {device,class}_destroy and unregister_chrdev functions may
be called with 'invalid' data perfectly fine. This means that this
variable is not needed and can safely be removed which is what this

Now, since the polling shall be implemented as a board specific feature
rather than being global in the driver this counter is obsolete.

Reported by Dan Carpenter <dan.carpenter@oracle.com>

outsize = sizeof(*gfout) + gfin->gf_pathlen;

Where outsize is int and gf_pathlen is u32 from userspace
can lead to integer overflowwhere outsize is some small number
less than sizeof(*gfout)

Add a check for pathlen to be of sensical size.

staging/lustre/llite: Make sure ft_flags is valid

In ll_fault0, the 'fault' struct is mostly cleared before the call to
cl_io_loop, but ft_flags is not reset. It is ordinarily set by
the call to filemap_fault in vvp_io_kernel_fault, but if Lustre
returns before calling filemap_fault, it still has the old value of
ft_flags.

ll_fault0 will then consume the ft_flags field. If it has the
VM_FAULT_RETRY bit set, it will be used as ll_fault0() and
ll_fault()'s return value.

This is a problem when VM_FAULT_RETRY is in ft_flags:
When fault/filemap_fault return with that flag set, they have already
released the mmap semaphore, and do_page_fault does not need to
release it.
Incorrectly returning this flag from ll_fault means mmap_sem
is not upped in the kernel's do_page_fault().

In addition to clearing ft_flags, this patch does not use it unless
it is valid.  It's potentially misleading to return ft_flags in
"fault_ret" if ft_flags has not been set by filemap_fault.

This adds clarity, but does not change the current behavior:
When not valid, ft_flags is replaced by fault_ret, which is zero,
as is ft_flags when not set by filemap_fault.

staging: comedi: 8255: refactor how the (*io) function works

Currently, all users of is module that use the default (*io) function
pass an 'iobase' to subdev_8255_init() of the form:

  dev->iobase + OFFSET_TO_8255_BASE_REG

Now that the (*io) callback includes the comedi_device 'dev' pointer
the 'dev->iobase' does not need to be included.

Modify the default (*io) function, subdev_8255_io(), to automatically
add the dev->iobase to the address when reading/writing the port.

For aesthetics, rename the subdevice private data member to 'regbase'.
Also, rename the local variables in this module that are used to
access this member.

Add a comment in dev_8255_attach() about the 'iobase' that is passed
to subdev_8255_init(). For manually attached 8255 devices the io
region is requested with __comedi_request_region() which does not
set dev->iobase. For these devices the 'regbase' is actually the
'iobase'.

Remove the, now unnecessary, dev->iobase from all the callers of
subdev_8255_init(). There are a couple drivers that only passed the
dev->iobase. For those drivers pass a 'regbase' of 0x00.

Note that the das16m1 driver is a bit goofy. The devpriv->extra_iobase
is requested using __comedi_request_region() which does not set the
dev->iobase. But the starting address passed is dev->iobase + DAS16M1_82C55
so a 'regbase' of DAS16M1_82C55 is passed to subdev_8255_init().

staging: comedi: addi_apci_1564: tidy register map defines

This commit performs a final tidying of the register map defines, bringing
them to a state that is ready for merging into addi_apci_1564.c when the
time comes.  Actions performed include:

*Removes the APCI1564_ADDRESS_RANGE macro, which is no longer needed/used.
*Renames the APCI1564_DIGITAL_OP_{VCC,CC}_INTERRUPT_{ENABLE,DISABLE}
macros to shorter names which are more consistent with the digital input
interrupt macros.
*Fixes a typo in a comment (dev>iobase changed to dev->iobase).
*Renames the APCI1564_TCW_* macros to APCI1564_COUNTER_* names to more
accurately reflect that they are only offsets to counter registers (since
only the counters are offset from dev->iobase).

staging: comedi: addi_apci_1564: Remove in-driver watchdog support code

Starting with commit 1496e5961113 ("staging: comedi: addi_apci_1564: use
addi_watchdog module to init watchdog subdevice"), this driver uses the
addi_watchdog module to provide support for the watchdog subdevice.  Any
remaining watchdog code in-driver can and should be removed.

This will also make future work on the timer and counter subdevices easier.

staging: comedi: addi_apci_1564: remove apci1564_do_config

The DO config function served the purpose of configuring the diagnostic
interrupts for the board.  As the driver currently does not support
diagnostic interrupts, the digital output subdevice does not need an
insn_config operation and this function can be safely removed.

Staging: rtl8188eu: Removed unneeded code.

This patch removes some unneeded code.
1) kzalloc() allocates 4 extra bytes so that we can align the return
   value.  But actually the return value is already aligned so we can
   remove the + 4 and the call to N_BYTE_ALIGMENT().
2) The memset() isn't needed because kzalloc() zeroes the allocation.
