[Qemu-devel] [PATCH for-3.2 v3 10/14] qdev-props: call object_apply_global_props()
Posted by Marc-André Lureau 7 years, 3 months ago 
It's now possible to use the common function.

Teach object_apply_global_props() to warn if Error argument is NULL.

arguably, it's up to caller to decide it warn or not.
I'd leave it warning code out of object_apply_global_props() and let caller do the job

The problem is that there may be multiple errors, and the remaining
globals should be applied.

I'll add a comment.
