This fixes gcc warnings when -Wextra is used: ../fs/jffs2/nodelist.c:255:37: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body] ../fs/jffs2/nodelist.c:278:38: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body] ../fs/jffs2/nodelist.c:558:52: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body] ../fs/jffs2/xattr.c:1247:58: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body] ../fs/jffs2/xattr.c:1281:65: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body] Builds without warnings on all 3 levels of CONFIG_JFFS2_FS_DEBUG.
