Is it a bugfix? The property is mandatory right now?

With recent kernel, yes. It is mandatory for the mode to be become available.

So it looks like bugfix. Can you resend the patch with: 1. cc-stable and fixes tags, 2. observable bug/issue/error (error from dmesg would be enough)?
It looks quite similar to 242ddf0429
