[patch-kj] use list_for_each() in fs/jffs/intrep.c

[maximilian attems <janitor@sternwelten.at>]

Use list_for_each() where applicable
- for (list = ymf_devs.next; list != &ymf_devs; list = list->next) {
+ list_for_each(list, &ymf_devs) {
pure cosmetic change, defined as a preprocessor macro in:
include/linux/list.h

applies cleanly to 2.6.8-rc2
