This is a note to let you know that I've just added the patch titled crypto: caam - fix RNG deinstantiation error checking to the 4.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: crypto-caam-fix-rng-deinstantiation-error-checking.patch and it can be found in the queue-4.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 40c98cb57cdbc377456116ad4582c89e329721b0 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Horia=20Geant=C4=83?= <horia.geanta@xxxxxxx> Date: Wed, 5 Apr 2017 11:41:03 +0300 Subject: crypto: caam - fix RNG deinstantiation error checking MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit From: Horia Geantă <horia.geanta@xxxxxxx> commit 40c98cb57cdbc377456116ad4582c89e329721b0 upstream. RNG instantiation was previously fixed by commit 62743a4145bb9 ("crypto: caam - fix RNG init descriptor ret. code checking") while deinstantiation was not addressed. Since the descriptors used are similar, in the sense that they both end with a JUMP HALT command, checking for errors should be similar too, i.e. status code 7000_0000h should be considered successful.
