4.2.8-ckt12 -stable review patch. If anyone has any objections, please let me know.
---8<------------------------------------------------------------
From: Dan Carpenter <redacted>
commit 60587bd0680507f48ae3a7360983228fd207de8a upstream.
The "handled" variable could be uninitialized if the
interrupt_service_routine() call back hasn't been implimented or if it
has been implemented but doesn't initialize "handled" to zero at the
start. For example, adv76xx_isr() only sets "handled" to true.
Fixes: 44b153ca639f ('[media] m5mols: Add ISO sensitivity controls')
