From: Leon He <leon.he@unisoc.com>

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