Commit Message

Dario Binacchi Nov. 16, 2024, 6:02 p.m. UTC 
The hi3110_can_ist() function was incorrectly incrementing only the
receive error counter, even in cases of bit or acknowledgment errors that
occur during transmission. The patch fixes the issue by incrementing the
appropriate counter based on the type of error.

Fixes: 57e83fb9b746 ("can: hi311x: Add Holt HI-311x CAN driver")
