Merge tag 'linux-can-fixes-for-3.14-20140129' of git://gitorious.org/linux-can/linux-can
linux-can-fixes-for-3.14-20140129 Marc Kleine-Budde says: ==================== Arnd Bergmann provides a fix for the flexcan driver, enabling compilation on all combinations of big and little endian on ARM and PowerPc. A patch by Ira W. Snyder fixes uninitialized variable warnings in the janz-ican3 driver. Rostislav Lisovy contributes a patch to propagate the SO_PRIORITY of raw sockets to skbs. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
