Subject: [PATCH v8 06/33] crypto: rockchip: add fallback for cipher
Date: Wed,  6 Jul 2022 09:03:45 +0000	[thread overview]
Message-ID: <20220706090412.806101-7-clabbe@baylibre.com> (raw)
In-Reply-To: <20220706090412.806101-1-clabbe@baylibre.com>

The hardware does not handle 0 size length request, let's add a
fallback.
Furthermore fallback will be used for all unaligned case the hardware
cannot handle.

Subject: [PATCH v8 06/33] crypto: rockchip: add fallback for cipher
Date: Wed,  6 Jul 2022 09:03:45 +0000	[thread overview]
Message-ID: <20220706090412.806101-7-clabbe@baylibre.com> (raw)
In-Reply-To: <20220706090412.806101-1-clabbe@baylibre.com>

The hardware does not handle 0 size length request, let's add a
fallback.
Furthermore fallback will be used for all unaligned case the hardware
cannot handle.

Fixes: ce0183cb6464b ("crypto: rockchip - switch to skcipher API")
