From d3c2be9022d687cc97c0798c4593382f1a22c068 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Tomislav=20Po=C5=BEega?= Date: Thu, 14 Mar 2019 15:07:50 +0100 Subject: [PATCH] ath9k: drop redundant code in ar9003_hw_set_channel MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit AR9330, AR9485, AR9531, AR9550, AR9561 and AR9565 all use same channel set register configuration which allows for small code size reduction.
