Description
In the Linux kernel, the following vulnerability has been resolved:

mtd: virt_concat: fix use-after-free in mtd_virt_concat_destroy()

mtd_concat_destroy() frees item->concat so calling
mtd_virt_concat_put_mtd_devices(item->concat) after that leads to a
use-after-free.

Fix it by moving mtd_virt_concat_put_mtd_devices() before
mtd_concat_destroy().
