From a9b2c8ef1585e1f14cec03777b1238e0d5ec4ea1 Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Fri, 23 Sep 2011 02:12:46 +0000 Subject: [PATCH] net/fec: fec_reset_phy() does not need to always succeed FEC can work without a phy reset on some platforms, which means not very platform necessarily have a phy-reset gpio encoded in device tree. Even on the platforms that have the gpio, FEC can work without resetting phy for some cases, e.g. boot loader has done that. So it makes more sense to have the phy-reset-gpio request failure as a debug message rather than a warning, and get fec_reset_phy() return void since the caller does not check the return anyway.
