From: Stephen Hemminger Date: Thu, 16 Apr 2015 23:23:39 +0000 (-0700) Subject: pci: make device id tables const X-Git-Tag: spdx-start~9303 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=6065355a03fc;p=dpdk.git pci: make device id tables const The PCI device id table is immutable and should be made const in all drivers. The pseudo drivers can initialize their local copy as necessary.
