V4L/DVB (13300): gspca - pac7302/pac7311: Separate the two subdrivers.

All PAC7311 specific functions remain in pac7311.c. All PAC7302 specific
functions are moved to pac7302.c. The USB device table is also divided into
two parts. This makes it possible to remove the sensor specific decisions
from different functions and also remove sensor infromation from the USB
device table.

The common functions are just copied to both subdrivers. These common
functions can be separated later to a common file or helper module.

V4L/DVB (13262): tda18271: fix regression preventing std map override from taking effect

In the changeset entitled, "tda18271: add support for the set_config method",
the initialization order was changed such that the standard map overrides
were being applied before loading the default standard map, based on the
stepping of the silicon. This changeset restores the proper order by
processing the standard map overrides both within the tda18271_set_config()
and the tda18271_attach() functions, after we read the id register of the
tuner.

Thanks to Michael Obst for his testing, helping me to identify the regression.

V4L/DVB (13238): v4l2_subdev: rename tuner s_standby operation to core s_power

Upcoming I2C v4l2_subdev drivers need a way to control the subdevice
power state from the core. This use case is already partially covered by
the tuner s_standby operation, but no way to explicitly come back from
the standby state is available.

Rename the tuner s_standby operation to core s_power, and fix tuner
drivers accordingly. The tuner core will call s_power(0) instead of
s_standby(). No explicit call to s_power(1) is required for tuners as
they are supposed to wake up from standby automatically.

V4L/DVB (13236): ir-kbd-i2c: Don't reject unknown I2C addresses

I do not think it makes sense any longer for ir-kbd-i2c to reject

addresses to ir-kbd-i2c so that they aren't rejected is a pain we
don't need. Unsupported devices will be spotted a few lines later
anyway.

This already lets us unlist 2 addresses (0x7a and 0x2d) for which
handling details are always provided by the caller (saa7134-input).
Hopefully we can remove more in the future.

V4L/DVB (13234): IR device at I2C address 0x7a

The i2c core prevents us from probing I2C address 0x7a because it's
not a valid 7-bit address (reserved for 10-bit addressing.) So we must
stop probing this address, and explicitly list all adapters which use
it. Under the assumption that only the Upmost Purple TV adapter uses
this invalid address, this fix should do the trick.

V4L/DVB (13224): pvrusb2: Improve diagnostic info on driver initialization failure

It used to be that the only real detectable reason for the driver to
fail during initialization would be that if the hardware is simply
jammed.  However with the advent of the sub-device mechanism in V4L it
is possible now to detect if a sub-device module fails to load
successfully.  The pvrusb2 driver does in fact react to this by also
(correctly) failing, however the original diagnostic message "hardware
is jammed" was still being reported.  This misleads the user because
in fact it might not actually be a hardware failure.  This change adds
logic to tell the difference and then report a more appropriate
message to the kernel log.

V4L/DVB (13165): videobuf do not force buffer size to be multiple of PAGE_SIZE

When the image size (bytesperline*height) is not multiple
of PAGE_SIZE, v4l2 rounded the required buffer size to
be multiple of PAGE_SIZE. This prevented user space
to store images directly into userptr buffers which were
not multiple of PAGE_SIZE. This constraint is removed.

The start address is still assumed to be required
page-aligned, ie., when v4l2 allocates mmap buffers,
the offset between different buffers is page-aligned.

1,If usb_buffer_alloc can't allocate a buffer sucessfully,
uvc_free_urb_buffers will be called to free the allocated
buffers, and stream->urb_size is required to be passed to
usb_buffer_free;

2,uvc_free_urb_buffers can reset stream->urb_size.
