Marc Kleine-Budde says:
====================
pull-request: can-next 2023-10-05
The first patch is by Miquel Raynal and fixes a comment in the sja1000
driver.
Vincent Mailhol contributes 2 patches that fix W=1 compiler warnings
in the etas_es58x driver.
Jiapeng Chong's patch removes an unneeded NULL pointer check before
dev_put() in the CAN raw protocol.
A patch by Justin Stittreplaces a strncpy() by strscpy() in the
peak_pci sja1000 driver.
The next 5 patches are by me and fix the can_restart() handler and
replace BUG_ON()s in the CAN dev helpers with proper error handling.
The last 27 patches are also by me and target the at91_can driver.
First a new helper function is introduced, the at91_can driver is
cleaned up and updated to use the rx-offload helper.
