patch with file mode change only cannot be parsed?

[Bin Meng]

Hi,

I noticed that if a patch contains only file mode changes like:

mode change 100755 => 100644

I suspect patchwork cannot parse it hence it just drops such patch?

An example:
https://lists.nongnu.org/archive/html/qemu-devel/2019-09/msg01210.html

And patchwork missed this patch in its series:
http://patchwork.ozlabs.org/project/qemu-devel/list/?series=129493

Regards,
Bin
