Greg Kroah-Hartman 78a66b00d9 Third round of new IIO drivers, cleanups and functionality for the 4.2 cycle.
Given Linus announced a 4.8rc coming up, hopefully time for one more
 lot of IIO patches this cycle.  Some of these are actually
 improvements / fixes for patches earlier in the cycle.
 
 New device support
 * st_accel driver - support devices with 8 bit channels.
 
 Cleanup
 * A general cleanup of the iio tools under /tools/ from Hartmut.
   I'm more than a little embarassed by how bad some of these were! Are well,
   much more refined and less bug prone now.
   These cover lots of stuff like unhandled error returns, memory leaks as
   well as general refactoring to tidy the code up.
 * iio_simple_dummy - fix memory leaks in the init functions, drop some
   pointless error returns from functions that never generate errors and
   make the module parameter explicitly unsigned.
 * More buffer handling reworks from Lars-Peter, this time targetting hardware
   buffers (a little used corner that looks likely to get more use in the near
   future). Specifically:
   - Always compute the masklength as inkernel buffer users may need it.
   - Add a means of labeling which buffer modes a given buffer implementation
     supports.
   - In the case of hardware buffers, require strict scan matching rather than
     matching to a superset.  Currently the demux is bypassed by these drivers
     (this may well not change for efficiency reasons) so allowing a superset
     of channels to be selected would otherwise lead to more data than requested
     confusing userspace.
 
 Driver funcationality improvments
 * mmc35240 - adds a compensation to the raw values as borrowed form Memsic's
   own input driver.
 * mma8452
   - event support
   - event debouncing
   - high  pass filter configuration
   - triggers
 * vf610 - allow conversion mode to be adjusted
 
 Fixlets
 * mmc35240
   - Off by one error that by coincidence had no real effect.
   - i2c_device_name should be lowercase.
   - Lack of null terminator at end of attributes array.
   - Avoid computing the fractional part of the magnetic field by moving
     the scaling into userspace where floating point is available to simplify
     the maths.
   - Use a smaller sleep before assuming the measurement is done.  This is
     safe and improves the possible polling rate.
   - Fix sensitivity on z-axis - datasheet disagrees with Memsic's releasedd
     code and the value used in the code seems to be correct.
 * stk3310 - make a local variable signed to ensure error handling works.
 * twl4030
   - fix calculation of the temperature sense current - bug unlikely
     to have ever been noticed as the difference is small.
   - Fix errors in descriptions.
