Subject: [PATCH 1/2] can: Added constants containing length of CAN identifiers
Date: Fri, 25 May 2012 11:12:36 +0200 [thread overview]
Message-ID: <1337937157-7680-1-git-send-email-lisovy@gmail.com> (raw)
The necessary information might be determined out of the CAN_*_MASK,
however it is undesirable to misuse masks for such purpose.
