RC_BIT_ALL explicitely lists each single currently defined protocol bit.
To simplify the code and make adding a protocol easier set each bit
no matter whether the respective protocol is defined yet.
RC_BIT_ALL is only used in checks whether a particular protocol is allowed
therefore it has no impact if bits for not (yet) defined protocols
are set.

To me this seems to be a bug in cx23885.
Variable allowed_protos should be of type u64 instead of unsigned long
because its value later is assigned to rc->allowed_protocols which is
of type u64.
If you agree I'd send a patch.

I guess we used to do that, but we decided to explicitly define all
protocols there. Can't remember why.
So, for now, I'm not applying this one. Also, it depends on patch 6/8,
due to RC_BIT_LIRC.
So, I'm not applying this one.
