Merge tag 'ieee802154-for-net-2023-06-19' of git://git.kernel.org/pub/scm/linux/kernel/git/wpan/wpan
Stefan Schmidt says: ==================== An update from ieee802154 for your *net* tree: Two small fixes and MAINTAINERS update this time. Azeem Shaikh ensured consistent use of strscpy through the tree and fixed the usage in our trace.h. Chen Aotian fixed a potential memory leak in the hwsim simulator for ieee802154. Miquel Raynal updated the MAINATINERS file with the new team git tree locations and patchwork URLs. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
