No. I'm speaking for myself, and that includes a lot of what people on
LKML have already said.

All the Android community had to do is push the drivers *without*
suspend blockers, then the Android kernel wouldn't be so different and
thus wouldn't be considered a fork. AFAIU the kernel side wakelocks
are already in the kernel, so there's no excuse not to merge the
drivers.

Then people would stop blaming Google for forking the kernel.

Nobody from the "media" cares about suspend blockers; they are a small
patch which cannot be considered a fork, more like a hack, like many
other platforms have.
