As a nit - might be better to keep check_params() intact,
and put this new check above into a separate function?
check_eh_conf() or so?
Another thing it seems a bit clumsy construction to have global var (scheduler_type)
just to figure out was particular option present on command line or not.
Probably simler way to avoid it - set initially em_conf->ext_params.sched_type to
some invalid value (-1 or so). Then after parse args you can check did its value
change or not.
As alternative thought: wouldn't it be better to unite both  --transfer-mode
and --schedule-type options into one?
Then possible values for this unite option would be:
"poll"
"event" (expands to "event-ordered")
"event-ordered"
"event-atomic"
"event-parallel"
And this situation you are checking above simply wouldn't be possible.
Again probably would be easier/simpler for users.

Wouldn't it be more natural to have these 2 functions below
(eh_conf_init(), eh_conf_uninit()) defined inside event_helper.c?

As I understand at that moment inline sessions already created on devices?
For consistency wouldn't it be better to do this check at parsing cfg file,
or straight after it?
