staging: Move media drivers to staging/media

2011-11-03T09:59:03+00:00

In practice, it is being hard to distinguish when a patch
should go to staging tree or to the media tree. Better
to distinguish it, by putting the media drivers at a
separate staging directory. Newer staging drivers that include
anything with "dvb*.h", "v4l2*.h" or "videodev2.h" should
go to the drivers/staging/media tree.

[media] ddbridge: fix compiler warnings

2011-09-06T17:42:59+00:00

'off' was unused and 'ret' really had to be used to return -EFAULT.

[media] drivers/media: do not use EXTRA_CFLAGS

2011-09-03T21:50:59+00:00

Usage of these flags has been deprecated for nearly 4 years by:

    commit f77bf01425b11947eeb3b5b54685212c302741b8
    Author: Sam Ravnborg 
    Date:   Mon Oct 15 22:25:06 2007 +0200

        kbuild: introduce ccflags-y, asflags-y and ldflags-y

Moreover, these flags (at least EXTRA_CFLAGS) have been documented for command
line use. By default, gmake(1) do not override command line setting, so this is
likely to result in build failure or unexpected behavior.

Replace their usage by Kbuild's `{as,cc,ld}flags-y'.

[media] ddbridge: fix ddb_ioctl()

2011-09-03T21:23:42+00:00

There were a several problems in this function:

1) Potential integer overflow in the comparison:
	if (fio.write_len + fio.read_len > 1028) {

2) If the user gave bogus values for write_len and read_len then
   returning -EINVAL is more appropriate than returning -ENOMEM.

3) wbuf was set to the address of an array and could never be NULL
   so I removed the pointless NULL check.

4) The call to vfree(wbuf) was improper.  That array is part of a
   larger struct and isn't allocated by itself.

5) flashio() can't actually fail, but we may as well add error
   handling in case this changes later.

6) In the default case where an ioctl is not implemented then
   returning -ENOTTY is more appropriate than returning -EFAULT.

[media] drxk: Move I2C address into a config structure

2011-07-27T20:55:48+00:00

Currently, the only parameter to be configured is the I2C
address. However, Terratec H5 logs shows that it needs a different
setting for some things, and it has its own firmware.

So, move the addr into a config structure, in order to allow adding
the required configuration bits.
