From f6adf410f70b6875ba6412e8909c742c3853201d Mon Sep 17 00:00:00 2001 From: Marc Kleine-Budde Date: Thu, 29 Sep 2022 10:01:22 +0200 Subject: [PATCH] can: gs_usb: gs_can_open(): sort checks for ctrlmode Sort the checks for dev->can.ctrlmode by values of CAN_CTRLMODE_*, so that it's clear where to add new checks. While there, remove the comment that the Atmel UC3C hardware doesn't support One Shot Mode. The One Shot mode is only available and to be activated by the user, if the device specifies the feature bit GS_CAN_FEATURE_ONE_SHOT.
