Merge tag 'staging-4.11-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging/IIO driver fixes from Greg KH: "Here are a few small staging and IIO driver fixes for issues that showed up after the big set if changes you merged last week. Nothing major, just small bugs resolved in some IIO drivers, a lustre allocation fix, and some RaspberryPi driver fixes for reported problems, as well as a MAINTAINERS entry update. All of these have been in linux-next for a week with no reported issues" * tag 'staging-4.11-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: staging: fsl-mc: fix warning in DT ranges parser MAINTAINERS: Remove Noralf Trønnes as fbtft maintainer staging: vchiq_2835_arm: Make cache-line-size a required DT property staging: bcm2835/mmal-vchiq: unlock on error in buffer_from_host() staging/lustre/lnet: Fix allocation size for sv_cpt_data iio: adc: xilinx: Fix error handling iio: 104-quad-8: Fix off-by-one error when addressing flag register iio: adc: handle unknow of_device_id data
