====================
pull-request: ieee802154 for net 2022-12-05

An update from ieee802154 for your *net* tree:

Three small fixes this time around.

Ziyang Xuan fixed an error code for a timeout during initialization of the
cc2520 driver.
Hauke Mehrtens fixed a crash in the ca8210 driver SPI communication due
uninitialized SPI structures.
Wei Yongjun added INIT_LIST_HEAD ieee802154_if_add() to avoid a potential
null pointer dereference.
