From 6a1197457f9ec085871d2f842e1bbbe9d13216da Mon Sep 17 00:00:00 2001 From: Hubert Chaumette Date: Tue, 22 Apr 2014 15:01:04 +0200 Subject: [PATCH] net/phy: micrel: fix bugged test on device tree loading for ksz9021 In ksz9021_load_values_from_of() val2 to val4 aren't tested against their initialization value. This causes the test to always succeed, and this value to be used as if it was loaded from the devicetree instead of being ignored, in case of a missing/invalid property in the ethernet OF device node. As a result, the value "0" is written to the relevant registers. Change the conditions to test against the right initialization value. Signed-off-by: Hubert Chaumette Signed-off-by: David S.
