This reverts commit e64c952e.

ATPX is the ACPI method for controlling AMD PowerXpress laptops.
There are flags to indicate which methods are supported.  If
the dGPU power down flag is not supported, the driver needs to
implement the dGPU power down manually.  We had previously
always forced the driver to assume the ATPX dGPU power down
was present, but this causes problems on boards where it is
not, leading to GPU hangs when attempting to power down the
dGPU.  Manual dGPU power down is not currently supported in
the Linux driver.  Some laptops indicate that the ATPX
dGPU power down method is not present, but it actually
apparently is.  I'm not sure if this is a bios bug and it should
be set or if there is a reason it was unset and the method should
not be used.  This is not an issue on other OSes since both the
ATPX and the manual driver power down methods are supported.

This is apparently fairly widespread, so just revert for now.

Commit 254d4d11 ("drm/exynos: Add dependency for G2D in Kconfig") made
the DRM_EXYNOS_G2D symbol to only be selectable if the s5p-g2d V4L2 driver
is not enabled, since both use the same HW IP block.

But added the dependency as depends on !VIDEO_SAMSUNG_S5P_G2D which isn't
correct since Kconfig expressions are not boolean but tristate. So it will
only evaluate to 'n' if VIDEO_SAMSUNG_S5P_G2D=y but it will evaluate to m
if VIDEO_SAMSUNG_S5P_G2D=m.

This means that both the V4L2 and DRM drivers can be enabled if the former
is enabled as a module, which is not what we want.

gcc-6 warns about a pointless loop in exynos_drm_subdrv_open:

drivers/gpu/drm/exynos/exynos_drm_core.c: In function 'exynos_drm_subdrv_open':
drivers/gpu/drm/exynos/exynos_drm_core.c:104:199: error: self-comparison always evaluates to false [-Werror=tautological-compare]
  list_for_each_entry_reverse(subdrv, &subdrv->list, list) {

Here, the list_for_each_entry_reverse immediately terminates because
the subdrv pointer is compared to itself as the loop end condition.

If we were to take the current subdrv pointer as the start of the
list (as we would do if list_for_each_entry_reverse() was not a macro),
we would iterate backwards over the &exynos_drm_subdrv_list anchor,
which would be even worse.

Instead, we need to use list_for_each_entry_continue_reverse()
to go back over each subdrv that was successfully opened until
the first entry.

This reverts commit 1028b55b.

It's broken: it makes ext4 return an error at an invalid point, causing
the readdir wrappers to write the the position of the last successful
directory entry into the position field, which means that the next
readdir will now return that last successful entry _again_.

You can only return fatal errors (that terminate the readdir directory
walk) from within the filesystem readdir functions, the "normal" errors
(that happen when the readdir buffer fills up, for example) happen in
the iterorator where we know the position of the actual failing entry.

I do have a very different patch that does the "signal_pending()"
handling inside the iterator function where it is allowable, but while
that one passes all the sanity checks, I screwed up something like four
times while emailing it out, so I'm not going to commit it today.

So my track record is not good enough, and the stars will have to align
better before that one gets committed.  And it would be good to get some
review too, of course, since celestial alignments are always an iffy
debugging model.

IOW, let's just revert the commit that caused the problem for now.

Pull GPIO fixes from Linus Walleij:
 "Here is a set of four GPIO fixes.  The two fixes to the core are

  Core fixes:

   - Defer GPIO device setup until after gpiolib is initialized.

     It turns out that a few very tightly integrated GPIO platform
     drivers initialize so early (befor core_initcall()) so that the
     gpiolib isn't even initialized itself.  That limits what the
     library can do, and we cannot reference uninitialized fields until
     later.

     Defer some of the initialization until right after the gpiolib is
     initialized in these (rare) cases.

   - As a consequence: do not use devm_* resources when allocating the
     states in the initial set-up of the gpiochip.

  Driver fixes:

   - In ACPI retrieveal: ignore GpioInt when looking for output GPIOs.

   - Fix legacy builds on the PXA without a backing pin controller.

   - Use correct datatype on pca953x register writes"
