Description

In the Linux kernel, the following vulnerability has been resolved:

mailbox: bcm2835: Fix timeout during suspend mode

During noirq suspend phase the Raspberry Pi power driver suffer of
firmware property timeouts. The reason is that the IRQ of the underlying
BCM2835 mailbox is disabled and rpi_firmware_property_list() will always
run into a timeout [1].

Since the VideoCore side isn’t consider as a wakeup source, set the
IRQF_NO_SUSPEND flag for the mailbox IRQ in order to keep it enabled
during suspend-resume cycle.
