Commit Message

Dario Binacchi Nov. 16, 2024, 6:02 p.m. UTC 
The f81604_handle_can_bus_errors() function only incremented the receive
error counter and never the transmit error counter, even if the ECC_DIR
flag reported that an error had occurred during transmission. The patch
increments the receive/transmit error counter based on the value of the
ECC_DIR flag.

Fixes: 88da17436973 ("can: usb: f81604: add Fintek F81604 support")
