Wrong log settings in can_stm32 driver

zephyr/drivers/can/can_stm32.c

Line 20 in 7786103

LOG_MODULE_DECLARE(can_driver, CONFIG_CAN_LOG_LEVEL);

It must be LOG_MODULE_REGISTER instead of LOG_MODULE_DEFINE.

LOG_MODULE_REGISTER(can_driver);
Is called in can_common.c:13.
You can only register a module once.

LOG_MODULE_DEFINE not worked for me with samples/can/driver

[alexanderwachter]

the sample builds without error on the latest HEAD.
west build -b nucleo_f746zg zephyr/samples/drivers/can

Sorry. It was my bad. It is not worked for me with my h7 can driver under dev. Thus I will close this issue. Your pointing on register in can_common will help me in investigation.

Found it out.

I've used LOG_MODULE_DECLARE(can_stm32h7_driver, CONFIG_CAN_LOG_LEVEL); with different name than can_driver, thus I need LOG_MODULE_DEFINE since it is not declared in can_common.c

BTW @Nukersson #31061 should work on the H7 too.

Thank you very much! I will try to help in PR pointed by you.
