The rx ring buffers are added to a hash table if firmare
support full rx reorder. If the full rx reorder support
flag is not set before allocating the rx ring buffers,
none of the buffers are added to the hash table. When we
unload the module, this hash table is checked for freeing
the allocated rx ring buffers. Since none of the rx ring buffers
were added to the hash table, this memory is leaked.
Set the rx full reorder support flag before we allocate
the rx ring buffer to avoid the memory leak.

Pointer from userspace is de-referenced before the command is checked.
This might cause a crash if the command being sent is not a valid command.
Hence changing the de-reference such that the pointer is accessed after
checking if a valid command is sent from the userspace.

This commit supports the case where the ION driver still hasn't

The size of the settings, copied from userspace, is directly checked
in msm_cci_data_queue with CCI_I2C_MAX_WRITE. This might cause
out of bound access in function msm_cci_data_queue as the max size is
MAX_I2C_REG_SET. Hence adding check on the size in flash driver itself.

When enabling animation/static splash in LK, drm/kms driver needs
to involve handoff code to support smooth transition. In display
driver's probe, it will do following items:
1. Check the status in LK for early splash.
2. Add data bus bandwidth voting in function sde_splash_init.
2. Handle SMMU mapping issue to avoid SMMU fault problem.
3. Bypass hardware reset to avoid glitch.
And after user's space is up, when first commit's vblank comes,
it will call functions to:
1. Tell LK to stop static/animation display and to exit.
2. Set early_domain_map_attr to 1 to enable stage 1 translation in
iommu driver.
3. Check the property of commit.If it's for HDMI, release HDMI
resource. If for DSI, release DSI resource.
4. Recycle the memory to be available to system.
5. Withdraw the bus bandwidth voting.
