Defer loading of the xc5000 firmware until it is actually needed.  This helps
on distros that have hald, which results in the device not being available
for use for around ten seconds in cases where the i2c bus is slow (such as
the HVR-950Q).  Also, the firmware load isn't really useful since we
immediately put the device to sleep afterward, which means a firmware reload
will be required anyway.

The xc5000 datasheet indicates that the reset pin only needs to be held low
for 10ms.  Reduce the value accordingly, which speeds up the firmware load
time a bit.

The GPIO's on the product can be in one of three places. To date we've
mainly used the GPIO's on the bridge itself, and once on the encoder.
Rather than having the complexity of multiple GPIO writes/reads from
isolated placed in the driver we'll route them through this function,
so we can make intelligent decisions about 1) Where the GPIO lives
and 2) Whether it conflicts (based on board) with some other function
to avoid bugs.

The i2c core used to maintain a list of client for each adapter. This
is a duplication of what the driver core already does, so this list
will be removed as part of a future cleanup. Anyone using this list
must stop doing so.

For pvrusb2, I propose the following change, which should lead to an
equally informative output. The only difference is that i2c clients
which are not a v4l2 subdev won't show up, but I guess this case is
not supposed to happen anyway.

Kick up the pvrusb2 version number advertised through the v4l

make a serious attempt to version the driver in this manner (otherwise
this one line becomes a nasty hotspot of changes and merge
conflicts).  The value that is here is really a historical thing.
However Hans Verkuil thought it might be a good idea to bump up the
number anyway right now since the driver's mechanism for communicating
with the v4l core has pretty much completely changed.  Sending out a

This change defines all possible "IR schemes" related to the pvrusb2

The V4L2 ioctls usually return 0 when the operation was successful
and -1 in case of error. Currently VIDIOC_REQBUFS returns the
number of buffers which is redundant because this information is
available in count field of struct v4l2_requestbuffers. The
V4L2 API specification, revision 0.24 [1] explicitly specifies for
VIDIOC_REQBUFS that the return value shall be 0 on success.

The patch was tested with v4l-test 0.13 [2] with vivi driver.
