Subject: [RFC 14/19] staging: qlge: rewrite do while loop as for loop in qlge_refill_bq
Date: Mon, 21 Jun 2021 21:48:57 +0800	[thread overview]
Message-ID: <20210621134902.83587-15-coiby.xu@gmail.com> (raw)
In-Reply-To: <20210621134902.83587-1-coiby.xu@gmail.com>

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