When a failure to stop a module in the pipeline is detected, the only
way to recover is to reset the ISP. However, as other users can be using
a different pipeline with other modules, the ISP can't be reset
synchronously with the error detection.
Mark the ISP as needing a reset when a failure to stop a pipeline is
detected, and reset the ISP when the last user releases the last
reference to the ISP.
Modify the omap3isp_pipeline_set_stream() function to record the new ISP
pipeline state only when no error occurs, except when stopping the
pipeline in which case the pipeline is still marked as stopped.

call subdev operations on the sensor and the CSI2 subdev. However,
this has broken multi-client set ups like the one on migor, because
that way all operations get called on both clients. To fix this add
a grp_id and set it to the client private context.

This keymap were used for the Hauppauge Black remote controller
only. It also contains some keycodes not found there. As the
Hauppauge Black is now part of the hauppauge keymap, just remove
it.
Also, remove the modprobe hacks to select between the Gray
and the Black versions of the remote controller as:
- Both are supported by default by the keymap;
- If the user just wants one keyboard supported,
it is just a matter of changing the keymap via
the userspace tool (ir-keytable), removing
the keys that he doesn't desire. As ir-keytable
auto-loads the keys via udev, this is better than
obscure modprobe parameters.

The rc-hauppauge-new map is a messy thing, as it bundles 3
different remote controllers as if they were just one,
discarding the address byte. Also, some key maps are wrong.
With the conversion to the new rc-core, it is likely that
most of the devices won't be working properly, as the i2c
driver and the raw decoders are now providing 16 bits for
the remote, instead of just 8.

There are two "hauppauge-new" keymaps, one with protocol
unknown, and the other with the protocol marked accordingly.
However, both tables are miss-named.
Also, the old rc-hauppauge-new is broken, as it mixes
three different controllers as if they were just one.
This patch solves half of the problem by renaming the
correct keycode table as just rc-hauppauge. This table
contains the codes for the four different types of
remote controllers found on Hauppauge cards, properly
mapped with their different addresses.

As the code in saa7134-input is not a module, but the config for it is
set as a boolean instead of a tristate, this causes a strange dependency
on RC_CORE.
VIDEO_SAA7134_RC (which determines if saa7134-input.o is built) depends
on RC_CORE and VIDEO_SAA7134. If VIDEO_SAA7134 is compiled as 'y' but
RC_CORE is compiled as 'm' VIDEO_SAA7134_RC can still be set to 'y'
which causes undefined symbols that it needs from RC_CORE.
The simplest solution is to not allow VIDEO_SAA7134_RC be enabled if
RC_CORE compiled as a module (m) and VIDEO_SA7134 is compiled into the
kernel (y).

The video_device struct has proper ref counting and its release function
will be called when the last user releases it. But no such support was
available for struct v4l2_device. This made it hard to determine when a
USB driver can release the device if it has multiple device nodes.
With one device node it is easy of course, since when the device node is
released, the whole device can be released.
This patch adds refcounting to v4l2_device. When registering device nodes
the v4l2_device refcount will be increased, when releasing device nodes
it will be decreased. The (optional) release function will be called when
the last device node was released.
