Marc Kleine-Budde 2dd5177598 can: raw: raw_setsockopt: limit number of can_filter that can be set 
commit 332b05ca7a upstream.

This patch adds a check to limit the number of can_filters that can be
set via setsockopt on CAN_RAW sockets. Otherwise allocations > MAX_ORDER
are not prevented resulting in a warning.
