[PATCH v2 11/14] vfio/mdev: Make to_mdev_device() into a static inline

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The macro wrongly uses 'dev' as both the macro argument and the member
name, which means it fails compilation if any caller uses a word other
than 'dev' as the single argument. Fix this defect by making it into
proper static inline, which is more clear and typesafe anyhow.
