Subject: [PATCH] can: esd_usb2: Fix can_dlc value for received RTR, frames
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

commit 72d92e865d1560723e1957ee3f393688c49ca5bf upstream.

The dlc member of the struct rx_msg contains also the ESD_RTR flag to
mark received RTR frames. Without the fix the can_dlc value for received
RTR frames would always be set to 8 by get_can_dlc() instead of the
received value.
