Subject: [PATCH net-next] cnic: Fix mmap regression.
Date: Fri, 29 Jun 2012 12:32:45 -0700	[thread overview]
Message-ID: <1340998365-15753-1-git-send-email-mchan@broadcom.com> (raw)

commit 1f85d58cdf15354a7120fc9ccc9bb9c45b53af88
    cnic: Remove uio mem[0].

introduced a regression as older versions of userspace app still rely
on this mmap.  Restore the mmap functionality and get the base address
from pci_resource_start() as the nedev->base_addr has been deprecated for
PCI devices.

Update version to 2.5.12.
