From a01df0fe5e4db8c272dcc395354884ff7c15fc10 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Sat, 5 Sep 2009 20:24:48 -0700 Subject: [PATCH] mlx4_core: Use pci_request_regions() The old code used two calls to pci_request_region() to get the two BARs for the mlx4 device, for no particularly good reason. Clean up the code a little by converting this to a single call to pci_request_regions().
