[PATCH] Update V4L2 "Hexium" driver
This updates my two Video4Linux-2 drivers for the "Hexium Gemini" and
"Hexium Orion" cards.
It adds the long missing input handling for the "Gemini" card and
removes the annoying compile time warning about unused structures.
- remove various hexium header files, put all driver relevant
informations into the drivers. these informations are not needed
anywhere else.
- fix driver names in information printk()s
- fix device initialization for Hexium Gemini cards
- add input switching for Hexium Gemini cards
- fix all remaining "fixme"s
