#     vfio-pci/nvlink2: Fix ancient gcc warnings
#     
#     Using the {0} construct as a generic initializer is perfectly fine in C,
#     however due to a bug in old gcc there is a warning:
#     
#       + /kisskb/src/drivers/vfio/pci/vfio_pci_nvlink2.c: warning: (near
#     initialization for 'cap.header') [-Wmissing-braces]:  => 181:9
#     
#     Since for whatever reason we still want to compile the modern kernel
#     with such an old gcc without warnings, this changes the capabilities
#     initialization.
#     
#     The gcc bugzilla: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53119
