It is hard to say what KEY_SCREEN and KEY_ZOOM mean, but historically DVB
folks have used them to indicate switch to full screen mode. Later, they
converged on using KEY_ZOOM to switch into full screen mode and KEY)SCREEN
to control aspect ratio (see Documentation/media/uapi/rc/rc-tables.rst).

Let's commit to these uses, and define:

- KEY_FULL_SCREEN (and make KEY_ZOOM its alias)
- KEY_ASPECT_RATIO (and make KEY_SCREEN its alias)

Please let me know how we want merge this. Some of patches can be applied
independently and I tried marking them as such, but some require new key
names from input.h

for the HID changes, and feel free to take it through your tree as a 
whole, I don't expect any major conflicts rising up from this.

Thanks,

Works for me too. My tests showed no issues, so that's OK from me.
