[igt-dev] [PATCH i-g-t 1/4] tests/sw_sync: fix pthread start_routine declaration

[Lucas De Marchi]

pthread_create() expects a void *(*start_routine) (void *). Fix warning
the following warning on gcc 8:

../tests/sw_sync.c:773:37: warning: cast between incompatible function types from ‘int (*)(void *)’ to ‘void * (*)(void *)’ [-Wcast-function-type]
   pthread_create(&threads[i], NULL, (void * (*)(void *))
                                     ^
