Subject: [PATCH 6/9] can: mcp251x: add LED trigger support
Date: Sun, 16 Dec 2012 12:08:30 +0100 [thread overview]
Message-ID: <1355656113-9562-7-git-send-email-fabio.baltieri@gmail.com> (raw)
In-Reply-To: <1355656113-9562-1-git-send-email-fabio.baltieri@gmail.com>
Add support for canbus activity led indicators on mcp251x devices by
calling appropriate can_led functions.
These are only enabled when CONFIG_CAN_LEDS is Y, becomes no-op
otherwise.
