Subject: [PATCH v5 17/33] crypto: rockchip: use read_poll_timeout
Date: Wed, 13 Apr 2022 19:06:57 +0000	[thread overview]
Message-ID: <20220413190713.1427956-18-clabbe@baylibre.com> (raw)
In-Reply-To: <20220413190713.1427956-1-clabbe@baylibre.com>

Use read_poll_timeout instead of open coding it.
In the same time, fix indentation of related comment.
