Subject: [PATCH v9 1/9] crypto: caam - allocate RNG instantiation descriptor with GFP_DMA
Date: Thu, 19 Mar 2020 09:12:25 -0700 [thread overview]
Message-ID: <20200319161233.8134-2-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20200319161233.8134-1-andrew.smirnov@gmail.com>
Be consistent with the rest of the codebase and use GFP_DMA when
allocating memory for a CAAM JR descriptor.
