strict-aliasing issue

[kusma]

tegra.c: In function 'lookup_bo':
tegra.c:48:2: warning: dereferencing type-punned pointer might break strict-aliasing rules [-Wstrict-aliasing]
  if (drmHashLookup(table, key, (void **)&bo))

I'm not convinced this is an actual issue, but I filed this to make sure I don't forget ;)

That warning occurs for every other drmHashLookup instance, I think it is bogus.
