Merge tag 'staging-4.5-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging and IIO driver fixes from Greg KH: "Here are some IIO and staging driver fixes for 4.5-rc3. All of them, except one, are for IIO drivers, and one is for a speakup driver fix caused by some earlier patches, to resolve a reported build failure" * tag 'staging-4.5-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: Staging: speakup: Fix allyesconfig build on mn10300 iio: dht11: Use boottime iio: ade7753: avoid uninitialized data iio: pressure: mpl115: fix temperature offset sign iio: imu: Fix dependencies for !HAS_IOMEM archs staging: iio: Fix dependencies for !HAS_IOMEM archs iio: adc: Fix dependencies for !HAS_IOMEM archs iio: inkern: fix a NULL dereference on error iio:adc:ti_am335x_adc Fix buffered mode by identifying as software buffer. iio: light: acpi-als: Report data as processed iio: dac: mcp4725: set iio name property in sysfs iio: add HAS_IOMEM dependency to VF610_ADC iio: add IIO_TRIGGER dependency to STK8BA50 iio: proximity: lidar: correct return value iio-light: Use a signed return type for ltr501_match_samp_freq()
