Subject: [PATCH] Revert "staging: sm7xxfb: remove driver"


Someone reported a bug in the function graph tracer for MIPS. As I'm
still waiting on my USB serial for my Imagination MIPS board, I decided
to bring my Lemote Yeeloong laptop back up to the latest kernel. This
is where I noticed that the screen no longer displays anything.

I ran a bisect, which came across a staging commit that removed the
sm7xxfb driver. When I reverted it on a v3.18-rc5 kernel and booted it
on my Lemote laptop, the display worked again.

I then did a search for this commit and found that Debian reverted it
too. Seems that there's still some Debian users of this laptop. (RMS?)

What needs to be done to make this a "proper" driver? I can try to
support it, although I have no idea how it works :-)

This reverts commit dc93c85235efa5201e9a3c116bc3fbd1afc1a182.
