If wait_event_interruptible_timeout returns a positive value, it means
the condition evaluated is true. Which means priv->shared->hw_running is false.
And then we will exit the loop.
This patch simplifies the logic to exit the while loop.

This patch converts the drivers in drivers/video/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled],
We run all interrupt handlers with interrupts disabled
and we even check and yell when an interrupt handler
returns with interrupts enabled (see commit [b738a50a:
genirq: Warn when handler enables interrupts]).
So now this flag is a NOOP and can be removed.

It was pointed out by 'make versioncheck' that some includes of
linux/version.h are not needed in drivers/video/.
This patch removes them.

Return -EFAULT instead of number of bytes that could not be copied if
copy_from_user() fails.
Also fix a typo in the comments.
