Merge tag 'staging-5.10-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
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
staging: octeon: Drop on uncorrectable alignment or FCS error
staging: octeon: repair "fixed-link" support
