staging: Move media drivers to staging/media
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.

Both ir-kbd-i2c and lirc_zilog provide support for RX events for +the chips supported by lirc_zilog. Before moving lirc_zilog out of staging: + +a. ir-kbd-i2c needs a module parameter added to allow the user to tell + ir-kbd-i2c to ignore Z8 IR units. + +b. lirc_zilog should provide Rx key presses to the rc core like ir-kbd-i2c + does. + + +2. lirc_zilog module ref-counting need examination.

Bridge drivers, if able, should provide a chip reset() callback +to lirc_zilog via struct IR_i2c_init_data. cx18 and ivtv already have routines +to perform Z8 chip resets via GPIO manipulations.
