  iio: light: hid-sensor-prox: Fix memory leak in probe() (2015-05-12 20:01:13 +0100)

----------------------------------------------------------------
The usual mixed bag of fixes for IIO in the 4.1 cycle.

Second version of this pull request as a small fix to a fix turned
up before Greg pulled it for a cc10001 patch near the top of the tree.

One core fix

* Set updated for a iio kfifo was incorrectly set to false during a failed
  update, resulting in atttempts to repeat the failed operation appearing
  to succeed.

This time I've decided to list the driver fixes in alphabetical order rather
than 'randomly'.

* axp288_adc - a recent change added a check for valid info masks when
  reading channels from consumer drivers.
* bmp280 - temperature compensation was failing to read the tfine value, hence
  causing a temperature of 0 to always be returned and incorrect presure
  measurements.
* cc10001 - Fix channel number mapping when some channels are reserved for
  remote CPUs. Fix an issue with the use of the power-up/power-down register
  (basically wrong polarity). Fix an issue due to the missinterpretting the
  return value from regulator_get_voltage. Add a delay before the start bit
  as recommended for the hardware to avoid data corruption.
* hid pressure - fix channel spec of modfiied, but no modifier (which makes no
  sense!)
* hid proximity - fix channel spec of modified, but no modifier (which makes
  no sense!). Fix a memory leak in the probe function.
* mcp320x - occasional incorrect readings on dma using spi busses due to
  cacheline corruption. Fixed by forcing ___cacheline_aligned for the buffers.
* mma9551 - buffer overrun fix (miss specified maximum length of buffers)
* mma9553 - endian fix on status message. Add an enable element for activity
  channel. Input checking for activity period to avoid rather unpredictable
  results.
* spmi-vadc - fix an overflow in the output value normalization seen on some
  boards.
* st-snesors - oops due to use of a mutex that is not yet initialized during
  probe.
* xilinx adc - Some wrong register addresses, a wrong address for vccaux
  channel, incorrect scale on VREFP and incorrect sign on VREFN.
