[LTP] [PATCH 1/4] tst_kernel: Add safe_check_driver()

[Petr Vorel]

Hi All,

In the end, I haven't used this function in the second commit,
thus this function is useless (used only on single place).
I'll remove it in v2 (still waiting for more input if whole .modprobe option is
worth of merging).

Kind regards,
Petr
