From 217a55a338262521d5106dafda2fe7bfff6583be Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Tue, 12 Feb 2013 23:14:51 +0000 Subject: [PATCH] bgmac: return error on failed PHY write MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Some callers may want to know if PHY write succeed. Also make PHY functions static, they are not exported anywhere. Signed-off-by: Rafał Miłecki Signed-off-by: David S.
