Merge tag 'iio-fixes-for-4.14a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus
Jonathan writes: First round of IIO fixes for the 4.14 cycle Note this includes fixes from recent merge window. As such the tree is based on top of a prior staging/staging-next tree. * iio core - return and error for a failed read_reg debugfs call rather than eating the error. * ad7192 - Use the dedicated reset function in the ad_sigma_delta library instead of an spi transfer with the data on the stack which could cause problems with DMA. * ad7793 - Implement a dedicate reset function in the ad_sigma_delta library and use it to correctly reset this part. * bme280 - ctrl_reg write must occur after any register writes for updates to take effect. * mcp320x - negative voltage readout was broken. - Fix an oops on module unload due to spi_set_drvdata not being called in probe. * st_magn - Fix the data ready line configuration for the lis3mdl. It is not configurable so the st_magn core was assuming it didn't exist and so wasn't consuming interrupts resulting in an unhandled interrupt. * stm32-adc - off by one error on max channels checking. * stm32-timer - preset should not be buffered - reorganising register writes avoids this. - fix a corner case in which write preset goes wrong when a timer is used first as a trigger then as a counter with preset. Odd case but you never know. * ti-ads1015 - Fix setting of comparator polarity by fixing bitfield definition. * twl4030 - Error path handling fix to cleanup in event of regulator registration failure. - Disable the vusb3v1 regulator correctly in error handling - Don't paper over a regulator enable failure.
