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.
