From d7eb33840bee3c8de3f64f3861350bcfac3eaf82 Mon Sep 17 00:00:00 2001 From: Bruce Allan Date: Wed, 8 Feb 2012 02:55:14 +0000 Subject: e1000e: potentially incorrect return for e1000_set_d3_lplu_state_ich8lan In the unlikely event that e1e_wphy() returns an error, the returned error code is not propogated to the caller of e1000_set_d3_lplu_state_ich8lan(). With this change, there is a rare possibility that ret_val might not get set so it must be initialized.
