Use the same fill_memory/fill_memory_ex interface in all affected tests. * tests/ioctl_block.c (init_magic): Remove. (main): Replace init_magic with fill_memory. * tests/ioctl_evdev.c: Likewise. * tests/ioctl_v4l2.c: Likewise. * tests/ioctl_mtd.c (magic, init_magic): Remove. (main): Replace init_magic with fill_memory. * tests/ioctl_rtc.c: Likewise.
