From bd0ccb92efb09c7da5b55162b283b42a93539ed7 Mon Sep 17 00:00:00 2001 From: Jeroen Hofstee Date: Fri, 27 Nov 2020 10:59:38 +0100 Subject: can: sja1000: sja1000_err(): don't count arbitration lose as an error Losing arbitration is normal in a CAN-bus network, it means that a higher priority frame is being send and the pending message will be retried later. Hence most driver only increment arbitration_lost, but the sja1000 driver also incremeants tx_error, causing errors to be reported on a normal functioning CAN-bus. So stop counting them as errors.
