ocfs2: remove kfree() redundant null checks
smatch analysis indicates a number of redundant NULL checks before calling kfree(), eg: fs/ocfs2/alloc.c:6138 ocfs2_begin_truncate_log_recovery() info: redundant null check on *tl_copy calling kfree() fs/ocfs2/alloc.c:6755 ocfs2_zero_range_for_truncate() info: redundant null check on pages calling kfree() etc.... [akpm@linux-foundation.org: revert dubious change in ocfs2_begin_truncate_log_recovery()] Signed-off-by: Tim Gardner <tim.gardner@canonical.com> Cc: Mark Fasheh <mfasheh@suse.com> Acked-by: Joel Becker <jlbec@evilplan.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
