Subject: [PATCH 01/18] crypto: caam - fix RNG init descriptor ret. code checking
Date: Mon,  3 Sep 2018 13:23:51 +0200	[thread overview]
Message-ID: <20180903112408.2086-2-m.niestroj@grinn-global.com> (raw)
In-Reply-To: <20180903112408.2086-1-m.niestroj@grinn-global.com>

Pick commit 62743a4145bb9c3fe090a48e10ddc0ebae85bfbf from Linux
upstream.

    crypto: caam - fix RNG init descriptor ret. code checking

    When successful, the descriptor that performs RNG initialization
    is allowed to return a status code of 7000_0000h, since last command
    in the descriptor is a JUMP HALT.
