CVE-2023-52660

In the Linux kernel, the following vulnerability has been resolved: media:
rkisp1: Fix IRQ handling due to shared interrupts The driver requests the
interrupts as IRQF_SHARED, so the interrupt handlers can be called at any
time. If such a call happens while the ISP is powered down, the SoC will
hang as the driver tries to access the ISP registers. This can be
reproduced even without the platform sharing the IRQ line: Enable
CONFIG_DEBUG_SHIRQ and unload the driver, and the board will hang. Fix this
by adding a new field, ‘irqs_enabled’, which is used to bail out from the
interrupt handler when the ISP is not operational.
