From 2a7f9982d6c188052b85a6488c7008a45c4a062c Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Tue, 13 May 2014 17:44:17 +0200 Subject: [PATCH] phy: sunxi: Rework phy initialization Move the phy initialization and variables declaration to the loop itself, since it is where it really belongs. Also remove all the temporary variables, we can use the structure members directly.
