Subject: RE: [PATCH v2 11/14] vfio/mdev: Make to_mdev_device() into a static inline
Date: Tue, 16 Mar 2021 08:10:02 +0000	[thread overview]

> 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.
