Marc Kleine-Budde says:

====================
pull-request: can 2022-12-19

The first patch is by Vincent Mailhol and adds the etas_es58x
devlink documentation to the index.

Haibo Chen's patch for the flexcan driver fixes a unbalanced
pm_runtime_enable warning.

The last patch is by me, targets the kvaser_usb driver and fixes
an error occurring with gcc-13.
