This defensive check is now required since the allocation
of driver private data has moved from bind to probe phase.
There is a chance that device shutdown can be called before
bind phase and this can cause invalid memory access.

If vblank work is queued to event thread, during modeset,
there might be a case where vblank is enabled in between
resulting in vblank ref count mismatch. This change queues
vblank request to disp thread during modeset.

msm_drv should be probe deferred until rsc driver
probe is done. OF_POPULATED flag only checks if platform
driver is registered and hence additional condition to
check if driver is attached to this device, is needed.

sync_state driver disables any resources that
don't have any votes after driver probe is completed.
Move MDSS resource votes to probe so that any resources
that are needed for continuous splash are intact until
the bind of all the components is complete.

Msm_drv device node has dependency on sde_rsc device
node for power resource enable if sde_rsc device
device is enabled. This change moves the msm_drv device
to probe defer state during component addition if
sde_rsc device is not probed yet. It also removes
the master_drm device node access from sde_rsc device.

There is potential byte alignment problem on 32bits OS which will
cause incorrect histogram blob id getting from the user space.
This change fixes byte alignment problem on 32bits OS by keeping
the struct members in one complete struct as the user space using.
In previous code start address of 'info' would align to multiple of 8,
so there would be 4 bytes padding between member 'event' and 'info'
on 32 bits OS. It is affected by member 'base'. But user space just
uses struct drm_msm_event_resp only, not affected by member 'base'.
Driver code intends to send drm_msm_event_resp, but actually send
unpacked members.

This change moves the msm_driver power resource initialization from
bind time to probe time. This keeps the resource vote on until all the
devices are bound. This is required since the regulator and clock
sync_state driver will remove the proxy votes as soon as msm_driver
has probed.

Currently the compression ratio is hard-coded to either 2:1 or
3:1 in several places. This is not sufficient for new compression
algorithms as they can support higher compression ratios.
Add support for calculating the compression ratios from the source

When trying to get the display up on my sdm845 board I noticed that
the display wouldn't probe if I had the dsi1 node marked as "disabled"
even though my board doesn't use dsi1. It looks like the msm code
adds all nodes to its list of components even if they are disabled. I
believe this doesn't work because all registered components need to
come up before we finish probing. Let's do like other DRM code and
only add available components.
