Subject: [RFC 12/19] staging: qlge: rewrite do while loops as for loops in qlge_start_rx_ring
Date: Mon, 21 Jun 2021 21:48:55 +0800	[thread overview]
Message-ID: <20210621134902.83587-13-coiby.xu@gmail.com> (raw)
In-Reply-To: <20210621134902.83587-1-coiby.xu@gmail.com>

Since MAX_DB_PAGES_PER_BQ > 0, the for loop is equivalent to do while
loop.
