Pull staging driver fixes from Greg KH:
 "Here are some small staging driver fixes for issues that have been
  reported in 5.10-rc1:

   - octeon driver fixes

   - wfx driver fixes

   - memory leak fix in vchiq driver

   - fieldbus driver bugfix

   - comedi driver bugfix

  All of these have been in linux-next with no reported issues"

* tag 'staging-5.10-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging:
  staging: fieldbus: anybuss: jump to correct label in an error path
  staging: wfx: fix test on return value of gpiod_get_value()
  staging: wfx: fix use of uninitialized pointer
  staging: mmal-vchiq: Fix memory leak for vchiq_instance
  staging: comedi: cb_pcidas: Allow 2-channel commands for AO subdevice
