4.2.8-ckt1 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: Ezequiel Garcia <ezequ...@vanguardiasur.com.ar>
commit a5d42b8c3b3ddccd88dc1c70957177d31a6699fb upstream.
When the diver is removed and all the resources are deallocated,
we should be iterating through the created devices only.
Currently, the iteration ends when vivid_devs[i] is NULL. Since
the array contains VIVID_MAX_DEVS elements, it will oops if
n_devs=VIVID_MAX_DEVS because in that case, no element is NULL.
Fixes: c88a96b023d8 ('[media] vivid: add core driver code')
