From 7d0f8eec976ae5a364af84fd8e92f6da9ec05a41 Mon Sep 17 00:00:00 2001 From: Dexuan Cui Date: Tue, 23 Aug 2016 04:46:39 +0000 Subject: [PATCH] PCI: hv: Use pci_function_description[0] in struct definitions The 2 structs can use a zero-length array here, because dynamic memory of the correct size is allocated in hv_pci_devices_present() and we don't need this extra element. No functional change.
