It is better to break IR and CI into different patches. Make easier for people to review.

You should likely patch also the Kconfig to auto-select en50221.

Use just:

Just put everything into a single line, if the size is lower than 80 cols.
Btw, it makes sense to put __func__ at the debug definition, instead of
needing to repeat it everywhere.

This is ugly. Instead, the better is to do something like:
buf[0] = enable? 0xff : 0;

You shouldn't use {} when there's just one condition. Also, you don't need an else here.
It would be better to write the above as:
if (1 == buf[0])
return DVB_CA_EN50221_POLL_CAM_PRESENT |
DVB_CA_EN50221_POLL_CAM_READY;
return 0;
