It'd be handy to be able to load module with parameters. E.g.:
tcrypt sec=1 mode=200
We have 2 options: to name strig by spaces to b:
./tst_check_drivers "tcrypt sec=1 mode=200" other_module
Or handle in tst_check_drivers.c just one module and call it several times.
None of them is elegant.
Otherwise LGTM.
Kind regards,
Petr
