Subject: [PATCH v4 5/8] crypto: sun4i-ss: initialize need_fallback
Date:   Mon, 14 Dec 2020 20:02:29 +0000
Message-Id: <20201214200232.17357-6-clabbe@baylibre.com>
In-Reply-To: <20201214200232.17357-1-clabbe@baylibre.com>
References: <20201214200232.17357-1-clabbe@baylibre.com>
Precedence: bulk

The need_fallback is never initialized and seem to be always true at runtime.
So all hardware operations are always bypassed.

Fixes: 0ae1f46c55f87 ("crypto: sun4i-ss - fallback when length is not multiple of blocksize")
