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.
