Hi,
Hooked up checkpatch to my testbuild-patch-series script.
Catched some issues, now trapped into what I think is a false positive:
ERROR: Macros with complex values should be enclosed in parenthesis
#995: FILE: include/hw/virtio/virtio-gpu.h:99:
+#define DEFINE_VIRTIO_GPU_PCI_PROPERTIES(_state) \
+ DEFINE_PROP_BIT("ioeventfd", _state, flags, \
+ VIRTIO_PCI_FLAG_USE_IOEVENTFD_BIT, false), \
+ DEFINE_PROP_UINT32("vectors", _state, nvectors, 4)
enclosing into parenthesis just isn't going to fly here as this is an
array snipped, not some piece of code we could wrap into the usual
"{ $code } while (0)".
cheers,
Gerd

Yes, I think we should just expect that checkpatch is sometimes
going to get confused by complex macros. It's never going to
be 100% accurate.
