X-Git-Tag: v4.9-rc1~92^2~1^6~3
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7d0f8eec976ae5a364af84fd8e92f6da9ec05a41;p=karo-tx-linux.git

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.
