<sigh> similar comment I make frequently now - stuff I know you know...
The ATTRIBUTE_NONNULL only matters if NULL is passed. There's no check
for whether the passed parameter is NULL.

In the long run, e.g. patch 7, it's one less indirection from
qemuAddSharedDevice to qemuAddSharedDisk for *ChangeEjectableMedia.

Of course there's an incredible irony that code uses *RemoveSharedDisk,
but yet no one up to this point saw fit to export *AddSharedDisk too.
