Subject: [PATCH 2/2] staging: wfx: drop useless loop
Date: Fri, 29 May 2020 14:16:03 +0200 [thread overview]
Message-ID: <20200529121603.1050891-2-Jerome.Pouiller@silabs.com> (raw)
In-Reply-To: <20200529121603.1050891-1-Jerome.Pouiller@silabs.com>
From: Jérôme Pouiller <jerome.pouiller@silabs.com>
It is guarantee that the loop will stop at first iteration. So drop the
loop.
Fixes: 6bf418c50f98a ("staging: wfx: change the way to choose frame to send")
