[Qemu-devel] [PULL 15/16] linux-user: Fix type for SIOCATMARK ioctl

[riku . voipio]

From: Peter Maydell <address@hidden>

The SIOCATMARK ioctl takes an argument which should be a
pointer to an integer where the kernel will write the result.
We were incorrectly declaring it as TYPE_NULL which would mean
it would always fail (with EFAULT) when it should succeed.
Correct the type.
