Sometimes platform/bridge drivers need to be notified when a control from
a sub-device changes value. In order to support this a notify callback was
added.

v4l2-compliance found problems with frequency clamping that wasn't
reported correctly and missing tuner index checks.
Also removed unnecessary tuner type checks (these are now done by the

The ir-i2c-kbd already adds I2C IR before the name. The way it is,
the devices are named as:
	"i2c IR (i2c IR (EM2840 Hauppaug"
With is ugly and incorrect. After this patch, it is now properly
displayed as:
	"i2c IR (WinTV USB2)"

If the device has an I2C IR, em28xx-rc should be loaded by default,
except if the user explicitly requested to not load, via modprobe
option.
Signed-off-by: NMauro Carvalho Chehab <mchehab@redhat.com>

The em28xx-input is used by 3 different types of input devices:
	- devices with buttons (like cameras and grabber devices);
	- devices with I2C remotes;
	- em2860 or latter chips with RC support embedded.
When the device has an I2C remote, all it needs to do is to call
the proper I2C driver (ir-i2c-kbd), passing the proper data to
it, and just leave the code.
Also, button devices have its own init code that doesn't depend on
having an IR or not (as a general rule, they don't have).
So, move its init code to fix bugs introduced by earlier patches
that prevent them to work.

- if kmalloc() returns NULL, we can return immediately without trying
   to kfree() a NULL pointer.
 - if i2c_transfer() fails, error out immediately instead of trying to
   upload the remaining bytes of the firmware.
 - the error code is then properly propagated down to ds3000_initfe().
