There are two errors in the dmabuf-heap selftest:
- The 'char name[5]' was not initialized to zero, which will cause strcmp(name, "vgem") failed in check_vgem().
- The return value of test_alloc_errors() should be reversed, other- wise the while loop in main() will be broken.

Please see my comment on v1 for this.

This change doesn't make sense. Initializing ret to 0 is a better way to go.
