From 1f1a5e78b09dace7a899045c1a51ded3042a5569 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Stefan=20M=C3=A4tje?= Date: Wed, 25 Aug 2021 23:52:27 +0200 Subject: [PATCH] can: usb: esd_usb2: esd_usb2_rx_event(): fix the interchange of the CAN RX and TX error counters MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit commit 044012b52029204900af9e4230263418427f4ba4 upstream. This patch fixes the interchanged fetch of the CAN RX and TX error counters from the ESD_EV_CAN_ERROR_EXT message. The RX error counter is really in struct rx_msg::data[2] and the TX error counter is in struct rx_msg::data[3].
