[LTP] [PATCH] Verify virtual device availability

Thinking about it twice, how about renaming the function safe_open_uinput()
and add tst_brk(TCONF, ...) there?

Function is not used in library where tst_brk(TCONF, ...) would be problematic,
therefore I would not even bother with having SAFE_OPEN_UINPUT() which would
evaluate open_uinput().

Kind regards,
Petr
