[PATCH 4.4 172/312] [media] cx23885: uninitialized variable in cx23885_av_work_handler()

[Greg Kroah-Hartman]

From: Dan Carpenter <dan.carpen...@oracle.com>

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')
