You know, the worst endianness errors are not the cases where
people forget to byte-swap, but the cases where they either byte-swap
with the wrong size, or byte-swap when they shouldn't have done so at
all. Those ones defeat the casual reader of the code.

Replaces Hans Verkuil by Andy Walls as the ivtv maintainer.
After 4 1/2 years, Hans decided to hand over the ivtv driver to Andy.
Andy was already doing more work on ivtv than him, so this just makes
official what was happening in practice.

Remove the following compiler warning: 'dummy' is used uninitialized in this function.
Although the result in the dummy variable is not used the program flow in
soc_camera_limit_side() depends on the value in dummy. The program flow is better
to be deterministic.

platform_get_irq returns -ENXIO on failure, so !irq was probably
always true. Better use (int)irq <= 0. Note that a return value of
zero is still handled as error even though this could mean irq0.
This is a followup to 305b3228f9 that
changed the return value of platform_get_irq from 0 to -ENXIO on error.

The Quickcam Web camera would not produce an image if you removed and inserted the module multiple times without physically power cycling the camera first.
By writing zero to bridge register STV_SCAN_RATE (0x1443) the camera works as intended, regardless of the number of module insertions.

This patch adds the ov511, quickcam_messenger, w9968cf, stv680 and ovcamchip
v4l1 drivers to the feature removal schedule as the devices they support
are now all also supported by v4l2 gspca sub drivers.
This patch also adds the v4l2 vc0301 driver for removal as it duplicates
functionality of the gspca_zc3xx driver, zc0301 only supports 2 USB-ID's
(because it only supports a limited set of sensors) wich are also
supported
by the gspca_zc3xx driver (which supports 53 USB-ID's in total).

Buffers were marked as done before being removed from the IRQ queue. If
a userspace application dequeued and requeued the buffer fast enough
during that time window, the buffer could end up being deleted twice,
generating an oops in interrupt context.
Add a new state, UVC_BUF_STATE_READY, to mark buffers as ready for reuse
but not yet removed from the queue, and transition to UVC_BUF_STATE_DONE
only when the buffer is removed from the queue.
