73019286cd staging/easycap: remove oss support
remove support for OSS. OSS is being deprecated
and it is just plain headache to support both alsa and oss.

Last I broke the compilation when OSS is enabled with the patch
cdaa898b5e
staging/easycap: kill telltale logic

so this fixes also that issue.

cdaa898b5e staging/easycap: kill telltale logic
This reason for this feature was

'some versions of the videodev module overwrite the data which has
been written by the call to usb_set_intfdata() in easycap_usb_probe(),
replacing it with a pointer to the embedded v4l2_device structure.
to detect this, the string in the easycap.telltale[] buffer is checked.'

The upstream version of v4l2_device_register sets driver data
only when it wasn't already set, therefore this is not needed

0de7586a11 Remove unneeded version.h includes (and add where needed) for drivers/staging/easycap/
It was pointed out by 'make versioncheck' that linux/version.h was not
always being included where needed and sometimes included needlessly
in drivers/staging/easycap/.
This patch fixes up the includes.

"""

bytes-per-pixel is stored in bits 5-7 of calculated mask.

But when calculating bytes-per-line we were extracting wrong value
instead of bytes-per-pixel, which was usually 2 times bigger -- e.g. for
PAL YUV 422 I was getting ((mask3 & 0x00F0) >> 4) = 4 bytes instead of 2.

The error here is that even in comments there is a line saying

     *     bytesperpixel IS         ((0x00E0 & easycap_format.mask) >> 5)

but we were using
                                    ((0x00F0 & easycap_format.mask) >> 4)

With 2 times bigger bytesperpixel and automatically bytesperline, the
video was shown halfheight'ed, which is understandable if we look at
video-memory layout:

    <------- bytesperline -------->
    <- real bpl ->

    x0----------y0  x1-----------y1
    x2----------y2  x3-----------y3

    xn----------yn  xn-----------yn
    <garbage>

for each line, we should display width pixels, then move to next line
with bytesperline, and oops, if bytesperline = 2*real-bytesperlin, we'll
skip one line and move to next-next line, and so only half lines will be
shown.

Initially I've debugged the problem with my video application[1], but
I've checked that after this patch both rawv (mine app) and tvtime work
correctly.

[1] http://repo.or.cz/w/rawv.git

P.S. why at all we use those mask/shifts? Why not use bitfields?

eb4cfaba54 staging/easycap: Fix thinko in "bars" module option description
Both bars=0 and bars=1 were described as meaning to display bars on
signal lost. Actually bars=1 means "display bars", but bars=0 means
display raw source as is (usually black screen).

Instead of changing bars=0 to "_no_ testcard bars ..." as suggested by
Dan Carpenter reword the whole bars description for clarity.

7ee40aadab [media] v4l: removal of old, obsolete ioctls
Some ioctl's were defined wrong on 2.6.2 and 2.6.6, using the wrong
type of R/W arguments. They were fixed, but the old ioctl names are
still there, maintained to avoid breaking binary compatibility:

There's no sense on preserving those forever, as it is very doubtful
that someone would try to use a such old binary with a modern kernel.
Removing them will allow us to remove some magic done at the V4L ioctl
handler.

Note that any application compiled with a videodev2.h from 2.6.7 or later
will be using the correct ioctls.
