Second set of IIO new drivers, functionality and cleanups for the 4.5 cycle.
The big one here is the configfs support which has been a long time in the
works but should allow for cleaner ways to do instantiation of those elements
of IIO that aren't directly connected to specific hardware. Lots of cool new
stuff we can use this for in the works!
New core stuff (basically all configfs support related)
* Configfs support
- Core support (was waiting for a configfs patch that went in around 4.4rc2)
- A little fixlet to add a configfs.h to contain a reference to the
configfs_subsystem structure.
* Some infrastructure to simplify handling of software based triggers
(i.e. ones with no actual hardware associated with them)
* A high resolution timer based trigger. This has been around for years
but until the configfs support was ready we didn't have a sensible way
of instantiating instances of it (the method used for the sysfs_trigger
has never been really satisfactory)
New Device Support
* AMS iAQ Volatile Organic Compounds sensor support.
* Freescale imx7d ADC driver
* Maxim MAX30100 oximeter driver (note that for these devices most of the
smart stuff will be in userspace - effectively they are just light sensors
with some interesting led synchronization as far as the kernel is concerned).
* Microchip mcp3421 support added to the mcp3422 driver.
* TI adc124s021 support added to the adc128s052 driver.
* TI ina219, inda226 power monitors. Note that there is an existing hwmon driver
for these parts, the usecase is somewhat different so it is unclear at this
point if the hwmon driver will eventually be replaced by a bridge from
this driver. In the meantime the Kconfig dependencies should prevent both
from being built.
New driver functionality
* us8152d power management support.
Cleanups, fixups
* Use list_for_each_entry_safe instead of list_for_each_safe with the entry
bit coded longhand.
* Select IRQ_WORK for IIO_DUMMY_EVGEN. This is a fix that somehow got lost
when the driver was moved so lets do it again.
* st-accel - drop an unused define.
* vz89x, lidar - optimize i2c transactions by using a single i2c tranfers
instead of multiple calls where supported (fall back to smbus calls as
before if not).
* Use dev_get_platdata() in staging drivers: tsl2x7x, adcs and frequency
drivers instead of direct access to the structure element.

counter mode register as a sequence of bitfield members. The struct
appears as the type of one of the members of `union cmReg`, the other
member of which is of type `unsigned short`, so the driver can
manipulate the register value as a whole, or as individual fields.
Although this is fairly convenient, it's not that conventional. The
code also needs to define the bitfield members in ascending or
descending order of the physical bits, depending on whether bitfields
are little- or big-endian.
Rip all that out and replace it with a bunch of macros to set and mask

staging: comedi: do extra checks for becoming non-busy for "write"
`comedi_write()` is the handler for the "write" file operation for
COMEDI devices. It mostly runs without using the main mutex of the
COMEDI device, but uses the `attach_lock` rw_semaphore to protect
against the COMEDI device becoming "detached". A file object can write
data for a COMEDI asynchonous command if it initiated the command. The
COMEDI subdevice is marked as busy when the command is started. At some
point, the "write" handler detects that the command has terminated and
so marks the subdevice as non-busy.
In order to mark the subdevice as non-busy, the "write" handler needs to
release the `attach_lock` rw_semaphore and `acquire the main `mutex`.
There is a vulnerable point between the two, so it checks that the
device is still attached after acquiring the mutex. However, it does
not currently check that the conditions for becoming non-busy still
hold. Add some more checks that the subdevice is still busy with a
command initiated by the same file object, and that the command is in
the correct direction (in case the subdevice supports both "read" and
"write").
