Please move these into adv7343_state. As far as I can tell these are purely
state variables and having these as statics prevents multiple instances of
this driver.

standards_info should either be const or moved to the state struct. Or split
into a const and a state part (probably the best course of action).

And is there a reason that there is no SECAM support?

Again, this belongs to the state struct.

to_state(sd)->ch_id is OK, no need for the extra '()' around it.

I can't help thinking that the config->output array is more of a
hindrance than a help. Isn't it much more understandable if you just do an
'old-fashioned' thing like:

if (std & A) {
        /* do whatever needs to be done to set the std to A */
} else if (std & B) {
        /* do whatever needs to be done to set the std to B */
} /* etc. */

It's also easier to comment the code in that case. I.e.: 'set Fsc to X MHz'.

Same comment really with regards to the config->output array.
