Merge tag 'staging-4.11-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging/IIO driver rfixes from Greg KH: "Here are a number of small IIO and staging driver fixes for 4.11-rc6. Nothing big here, just iio fixes for reported issues, and an ashmem fix for a very old bug that has been reported by a number of Android vendors" * tag 'staging-4.11-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: staging: android: ashmem: lseek failed due to no FMODE_LSEEK. iio: hid-sensor-attributes: Fix sensor property setting failure. iio: accel: hid-sensor-accel-3d: Fix duplicate scan index error iio: core: Fix IIO_VAL_FRACTIONAL_LOG2 for negative values iio: st_pressure: initialize lps22hb bootime iio: bmg160: reset chip when probing iio: cros_ec_sensors: Fix return value to get raw and calibbias data.
