[igt-dev] [PATCH i-g-t 2/7] lib/igt_fb: Call dumb_destroy ioctl in case of dumb buffers

[Deepak Rawat]

vmwgfx does not support GEM interface so calling gem_close on vmwgfx
results in error.

v2: Use drmIoctl with error when ioctl() failed.

The sop is to 

int __kmstest_dumb_destroy() (why would this be kmstest if it is just a
kms ioctl wrapper???)
{
	int err = 0;

	if (drmIoctl(fd, DRM_IOCTL_MODE_DESTROY_DUMB, &handle))
		err = -errno;
	
	errno = 0;
	return err;
}

void kmstest_dumb_destroy(int fd, u32 handle)
{
	igt_assert_eq(__kmstest_dumb_destroy(fd, handle), 0);
}
