Subject: [PATCH 3.5 45/64] can: dev: fix nlmsg size calculation in can_get_size()

3.5.7.24 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Marc Kleine-Budde <mkl@...gutronix.de>

commit fe119a05f8ca481623a8d02efcc984332e612528 upstream.

This patch fixes the calculation of the nlmsg size, by adding the missing
nla_total_size().
