UBI: add missing kmem_cache_free() in process_pool_aeb error path
I ran into this error after a ubiupdatevol, because I forgot to backport e9110361a9a4 UBI: fix the volumes tree sorting criteria. UBI error: process_pool_aeb: orphaned volume in fastmap pool UBI error: ubi_scan_fastmap: Attach by fastmap failed, doing a full scan! kmem_cache_destroy ubi_ainf_peb_slab: Slab cache still has objects CPU: 0 PID: 1 Comm: swapper Not tainted 3.14.18-00053-gf05cac8dbf85 #1 [<c000d298>] (unwind_backtrace) from [<c000baa8>] (show_stack+0x10/0x14) [<c000baa8>] (show_stack) from [<c01b7a68>] (destroy_ai+0x230/0x244) [<c01b7a68>] (destroy_ai) from [<c01b8fd4>] (ubi_attach+0x98/0x1ec) [<c01b8fd4>] (ubi_attach) from [<c01ade90>] (ubi_attach_mtd_dev+0x2b8/0x868) [<c01ade90>] (ubi_attach_mtd_dev) from [<c038b510>] (ubi_init+0x1dc/0x2ac) [<c038b510>] (ubi_init) from [<c0008860>] (do_one_initcall+0x94/0x140) [<c0008860>] (do_one_initcall) from [<c037aadc>] (kernel_init_freeable+0xe8/0x1b0) [<c037aadc>] (kernel_init_freeable) from [<c02730ac>] (kernel_init+0x8/0xe4) [<c02730ac>] (kernel_init) from [<c00093f0>] (ret_from_fork+0x14/0x24) UBI: scanning is finished Freeing the cache in the error path fixes the Slab error.
