mtd: ubi: wl: Fix error return code in ubi_wl_init()
Fix to return error code -ENOMEM from the kmem_cache_alloc() error handling case instead of 0, as done elsewhere in this function. Fixes: f78e5623f45b ("ubi: fastmap: Erase outdated anchor PEBs during attach") Signed-off-by: Wei Yongjun <weiyongjun1@huawei.com> Reviewed-by: Boris Brezillon <boris.brezillon@free-electrons.com> Signed-off-by: Richard Weinberger <richard@nod.at>
