3271d382c3 mfd: Use mfd cell platform_data for timberdale cells platform bits
With the addition of a device platform mfd_cell pointer, MFD drivers
can go back to passing platform data back to their sub drivers.
This allows for an mfd_cell->mfd_data removal and thus keep the
sub drivers MFD agnostic. This is mostly needed for non MFD aware
sub drivers.

c6ae804a65 [media] wl12xx: g_volatile_ctrl fix: wrong field set
The function g_volatile_ctrl should change the current value rather than the
new value. These two drivers didn't do that, so the value is never reported
correctly.

In the future this will change since this behavior is clearly unexpected,
but for now fix these drivers first.

80845a3316 [media] v4l: make sure drivers supply a zeroed struct v4l2_subdev
Some v4l drivers currently don't initialize their struct v4l2_subdev
with zeros, and this is a problem since some of the v4l2 code expects
this. One example is the addition of internal_ops in commit 45f6f84,
after that we are at risk of random oopses with these drivers when code
in v4l2_device_register_subdev tries to dereference sd->internal_ops->*,
as can be shown by the report at http://bugs.launchpad.net/bugs/745213
and analysis of its crash at https://lkml.org/lkml/2011/4/1/168

Use kzalloc within problematic drivers to ensure we have a zeroed struct
v4l2_subdev.

424852f437 [media] radio-gemtek-pci: remove duplicate driver
The radio-gemtek-pci driver is for the same hardware as the radio-maxiradio
driver which uses the same GemTek PR103 and tea5757 combination and the two
drivers are identical. I chose the maxiradio over the gemtek-pci driver since
the maxiradio has support for mono/stereo detection.

Tested with my gemtek-pci card.

b9218f2f15 [media] saa6588: rename rds.h to saa6588.h
The naming of the media/rds.h header suggested that it was a generic
RDS header, when in fact it is just a saa6588 module API that is
internal to the kernel.

Rename the header and the struct and defines in it to make this clear.

Also removed the header include in radio-si470x.h (not used anymore)
and from ioctl-number.txt (it's internal to the kernel and never called
from userspace).
