Subject: [PATCH 4.14 02/23] can: usb: esd_usb2: esd_usb2_rx_event(): fix the interchange of the CAN RX and TX error counters
Date: Wed,  1 Sep 2021 14:26:47 +0200	[thread overview]
Message-ID: <20210901122249.866177164@linuxfoundation.org> (raw)
In-Reply-To: <20210901122249.786673285@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")
