While introducing HDMI support, component matching on connectors node
were bypassed since no driver would actually bind on the DT node.
But when only a CVBS connector is present, only a single node is found
in the graph, but ignored and a NULL match table is given to the
component code.
This code permits bypassing the components framework by binding directly
the DRM driver when no components needs to be loaded.

The scanline counter is bonkers on VLV/CHV DSI. The scanline counter
increment is not lined up with the start of vblank like it is on
every other platform and output type. This causes problems for
both the vblank timestamping and atomic update vblank evasion.
On my FFRD8 machine at least, the scanline counter increment
happens about 1/3 of a scanline ahead of the start of vblank (which
is where all register latching happens still). That means we can't
trust the scanline counter to tell us whether we're in vblank or not
while we're on that particular line. In order to keep vblank
timestamping in working condition when called from the vblank irq,
we'll leave scanline_offset at one, which means that the entire
line containing the start of vblank is considered to be inside
the vblank.
For the vblank evasion we'll need to consider that entire line
to be bad, since we can't tell whether the registers already
got latched or not. And we can't actually use the start of vblank
interrupt to get us past that line as the interrupt would fire
too soon, and then we'd up waiting for the next start of vblank
instead. One way around that would using the frame start
interrupt instead since that wouldn't fire until the next
scanline, but that would require some bigger changes in the
interrupt code. So for simplicity we'll just poll until we get
past the bad line.
v2: Adjust the comments a bit

PCI / PM: Avoid resuming PCI devices during system suspend
PCI devices will default to allowing the system suspend complete
optimization where devices are not woken up during system suspend if
they were already runtime suspended. This however breaks the i915/HDA
drivers for two reasons:
- The i915 driver has system suspend specific steps that it needs to
run, that bring the device to a different state than its runtime
suspended state.
- The HDA driver's suspend handler requires power that it will request
from the i915 driver's power domain handler. This in turn requires the
i915 driver to runtime resume itself, but this won't be possible if the
suspend complete optimization is in effect: in this case the i915
runtime PM is disabled and trying to get an RPM reference returns
-EACCESS.
Solve this by requiring the PCI/PM core to resume the device during
system suspend which in effect disables the suspend complete optimization.
Regardless of the above commit the optimization stayed disabled for DRM
devices until

drm: Remove dev_pm_ops from drm_class
so this patch is in practice a fix for this commit. Another reason for
the bug staying hidden for so long is that the optimization for a device
is disabled if it's disabled for any of its children devices. i915 may
have a backlight device as its child which doesn't support runtime PM
and so doesn't allow the optimization either. So if this backlight
device got registered the bug stayed hidden.
Credits to Marta, Tomi and David who enabled pstore logging,
that caught one instance of this issue across a suspend/
resume-to-ram and Ville who rememberd that the optimization was enabled
for some devices at one point.

The previous attempt at this had an issue with with num_clips > 1
because it would always end up using the coordinates of the last
clip while using width and height calculated from the bounding
box of all the clips.
So if the last clip happens to be not at the top-left corner of
the bounding box, the CPU blit operation would go out of bounds.
The original intent was to coalesce all the clips into one blit,
and to do that we need to also track the starting point of the
content buffer.

When vmw_gb_surface_define_ioctl() is called with an existing buffer,
we end up returning an uninitialized variable in the backup_handle.
The fix is to first initialize backup_handle to 0 just to be sure, and
second, when a user-provided buffer is found, we will use the
req->buffer_handle as the backup_handle.
