## Description

In the Linux kernel, the following vulnerability has been resolved:  media: qcom: iris: use disable_irq() during power-off  The IRQ is registered as a threaded IRQ.  Using disable_irq_nosync() in iris_vpu_power_off() does not wait for an already queued threaded IRQ handler to complete before returning.  As a result, a threaded IRQ handler may still run after the VPU has been powered down and access hardware registers after power-off.  Replace disable_irq_nosync() with disable_irq() so the power-off path waits for any in-flight threaded IRQ handler to complete before returning.
