Subject: [PATCH 4.19 08/33] can: usb: esd_usb2: esd_usb2_rx_event(): fix the interchange of the CAN RX and TX error counters
Date: Wed, 1 Sep 2021 14:27:57 +0200 [thread overview]
Message-ID: <20210901122251.060612951@linuxfoundation.org> (raw)
In-Reply-To: <20210901122250.752620302@linuxfoundation.org>
From: Stefan Mätje <stefan.maetje@esd.eu>
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].
Fixes: 96d8e90382dc ("can: Add driver for esd CAN-USB/2 device")
