Merge branch 'ieee802154-for-davem-2019-04-25' of git://git.kernel.org/pub/scm/linux/kernel/git/sschmidt/wpan
Stefan Schmidt says: ==================== ieee802154 for net 2019-04-25 An update from ieee802154 for your *net* tree. Another fix from Kangjie Lu to ensure better checking regmap updates in the mcr20a driver. Nothing else I have pending for the final release. If there are any problems let me know. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
