vme: vme_ca91cx42.c: use list_for_each_safe() when delete list items
Since we will be removing items off the list using list_del() we need to use a safer version of the list_for_each() macro aptly named list_for_each_safe(). We should use the safe macro if the loop involves deletions of items. Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
