[LTP] [PATCH 1/1] recvmmsg01: Fix compilation

[Petr Vorel]

void* cannot be directly used, it must be pointing to the struct.

recvmmsg01.c:86:9: error: request for member ?type? in something not a
structure or union
  timeout.type = tv->ts_type;

Fixes: 135af8ede ("syscalls/{send|recv}mmsg: add a test case for timeout
and errno test")

Hi,

this is wrong, Xao's solution is better:

Kind regards,
