Merge tag 'staging-3.18-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging fixes from Greg KH:
"Here are some staging driver fixes for 3.18-rc3. Mostly iio and
comedi driver fixes for issues reported by people.
All of these have been in linux-next for a while with no reported
issues"
* tag 'staging-3.18-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging:
staging: comedi: fix memory leak / bad pointer freeing for chanlist
staging: comedi: Kconfig: fix config COMEDI_ADDI_APCI_3120 dependants
staging: comedi: widen subdevice number argument in ioctl handlers
staging: rtl8723au: Fix alignment of mac_addr for ether_addr_copy() usage
drivers/staging/comedi/Kconfig: Let COMEDI_II_PCI20KC depend on HAS_IOMEM
staging: comedi: (regression) channel list must be set for COMEDI_CMD ioctl
iio: adc: mxs-lradc: Disable the clock on probe failure
iio: st_sensors: Fix buffer copy
staging:iio:ad5933: Drop "raw" from channel names
