From ea58ceb543b45d45b257a86eaf9d60c94e8adcf2 Mon Sep 17 00:00:00 2001 From: David Howells Date: Tue, 15 Dec 2009 16:47:46 -0800 Subject: [PATCH] FS-Cache: Avoid maybe-used-uninitialised warning on variable 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.
