Subject: [PATCH 1/9] can: mark bittiming_const pointer in struct can_priv as const
Date: Fri, 20 Jul 2012 13:11:41 +0200 [thread overview]
Message-ID: <1342782709-4868-2-git-send-email-mkl@pengutronix.de> (raw)
In-Reply-To: <1342782709-4868-1-git-send-email-mkl@pengutronix.de>
This patch marks the bittiming_const pointer as in the struct can_pric as
"const". This allows us to mark the struct can_bittiming_const in the CAN
drivers as "const", too.
