Subject: [PATCH 6/8] crypto: sun8i-ss: remove redundant test
Date: Wed, 26 Jan 2022 21:04:39 +0000	[thread overview]
Message-ID: <20220126210441.3661782-7-clabbe@baylibre.com> (raw)
In-Reply-To: <20220126210441.3661782-1-clabbe@baylibre.com>

Some fallback tests were redundant with what sun8i_ss_hash_need_fallback() already do.
