Jonathan writes: 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.
