[PATCH v2] media: iris: use IRQF_NO_AUTOEN when requesting the IRQ

[Dmitry Baryshkov]

Requesting the IRQ and then immediately disabling it is fragile as it
leaves a window when the IRQ is still enabled although the underlying
device might be not completely setup for IRQ handling. Pass
IRQF_NO_AUTOEN instead of calling disable_irq_nosync().
