Pull staging/IIO fixes from Greg KH: "Here are some staging and IIO driver fixes for 4.10-rc3. Most of these are minor IIO fixes of reported issues, along with one network driver fix to resolve an issue. And a MAINTAINERS update with a new mailing list. All of these, except the MAINTAINERS file update, have been in linux-next with no reported issues (the MAINTAINERS patch happened on Friday...)" * tag 'staging-4.10-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: MAINTAINERS: add greybus subsystem mailing list staging: octeon: Call SET_NETDEV_DEV() iio: accel: st_accel: fix LIS3LV02 reading and scaling iio: common: st_sensors: fix channel data parsing iio: max44000: correct value in illuminance_integration_time_available iio: adc: TI_AM335X_ADC should depend on HAS_DMA iio: bmi160: Fix time needed to sleep after command execution iio: 104-quad-8: Fix active level mismatch for the preset enable option iio: 104-quad-8: Fix off-by-one errors when addressing IOR iio: 104-quad-8: Fix index control configuration
