[PATCH][net-next] qtnfmac: fix uninitialized return code in ret

From: Colin King
Date: Wed Jun 21 2017 - 09:25:53 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

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.

Detected by CoverityScan, CID#1437563 ("Unitialized scalar variable")
