From: Linus Walleij <linus.walleij@linaro.org>
[ Upstream commit 4a672d500bfd6bb87092c33d5a2572c3d0a1cf83 ]
Several device tree files get the polarity of the pendown-gpios
wrong: this signal is active low. Fix up all incorrect flags, so
that operating systems can rely on the flag being correctly set.

[ Upstream commit 4a059559809fd1ddbf16f847c4d2237309c08edf ]
Fix a wrong error return by dropping an error return.
When vidi driver is remvoed, if ctx->raw_edid isn't same as fake_edid_info
then only what we have to is to free ctx->raw_edid so that driver removing
can work correctly - it's not an error case.

[ Upstream commit 48bfd02569f5db49cc033f259e66d57aa6efc9a3 ]
If it is async, runqueue_node is freed in g2d_runqueue_worker on another
worker thread. So in extreme cases, if g2d_runqueue_worker runs first, and
then executes the following if statement, there will be use-after-free.
