[PATCH RESEND] crypto: make sure *blkcipher_walk_init properly initialises walk

2013-11-10 Thread Michal Nazarewicz
From: Michal Nazarewicz min...@mina86.com blkcipher_walk_init and ablkcipher_walk_init functions are called to initialise a walk structure allocated on stack, which is not initialised by the caller. This means, that the fields of the structure contain garbage when *_init is run. The *_init

[PATCH] powerpc: add explicit OF includes for ppc4xx

2013-11-10 Thread Rob Herring
From: Rob Herring rob.herr...@calxeda.com Commit b5b4bb3f6a11f9 (of: only include prom.h on sparc) removed implicit includes of of_*.h headers by powerpc's prom.h. Some PPC4xx components were missed in initial clean-up patch, so add the necessary includes to fix ppc4xx builds. Signed-off-by: Rob
