From 3e3d8aa611076efc945687df30a3abf181989d1d Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Wed, 21 Jun 2017 14:25:30 +0100 Subject: [PATCH] qtnfmac: fix uninitialized return code in ret The return value ret is unitialized and garbage is being returned for the three different error conditions when setting up the PCIe BARs. Fix this by initializing ret to -ENOMEM to indicate that the BARs failed to be setup correctly.
