Andrew Morton's compiler sees the following warning in FS-Cache:
fs/fscache/object-list.c: In function 'fscache_objlist_lookup':
fs/fscache/object-list.c:94: warning: 'obj' may be used uninitialized in this function
which my compiler doesn't. This is a false positive as obj can only be used
in the comparison against minobj if minobj has been set to something other
than NULL, but for that to happen, obj has to be first set to something.
Deal with this by preclearing obj too.
