Subject: [Intel-wired-lan] [PATCH v2 14/25] kdoc_parser: handle struct
member macro VIRTIO_DECLARE_FEATURES(name)

From: Randy Dunlap <redacted>

Parse the macro VIRTIO_DECLARE_FEATURES(name) and expand it to its
definition. These prevents one build warning:

WARNING: include/linux/virtio.h:188 struct member
'VIRTIO_DECLARE_FEATURES(features' not described in 'virtio_device'
