PXA suspend switches off DMA core, which loses all context
of previously assigned descriptors. As pxa_camera driver
relies on DMA transfers, setup the lost descriptors on
resume and retrigger frame acquisition if needed.

Add suspend/resume hooks to call soc operation specific
suspend and resume functions. This ensures the camera
chip has been previously resumed, as well as the camera
bus.
These hooks in camera chip drivers should save/restore
chip context between suspend and resume time.

So, platform_driver_unregister() doesn't actually have a return value,

quoting Robert Lowery:
I think I've found the cause of the oops.
[...]
BTW it appears I have fixed my tuning problems with the updated patch
below. This reverts a change Mauro made a while back.
All is good now :)

The good news is that I've got a better patch that definitely works this
time and even better, makes use of the standard firmware (rather than
the Australian specific one).

The crash is due to USB exchanges done at interrupt level.
These exchanges, tied to autogain, are now done by the application.

The offset field of the scatterlist entry *after* the last valid scatterlist
entry was used instead of the first scatterlist entry (as was the intention
of this code).
This worked fine until the kzalloc of the sglist was replaced with kmalloc
and sg_init_table only zeroed the exact needed length. Apparently kzalloc
zeroes a bit more than is strictly necessary so the offset field was
always 0 in the past.
But now the offset field was suddenly random and this led to broken captures.
