Cover letter [PATCH 0/2] drm/vc4: Correctly uninstall interrupts
This set of patches fixes issues with vc4_irq_uninstall. The first patch fixes a NULL pointer dereference when the binner BO would disappear during an in flight overflow mem work callback.
The second patch ensures we return with all interrupts disabled. This was suspected to cause the NULL dereference but turned out to be unrelated.
Tested with a Raspberry Pi CM 3 that was previously stuck in a boot loop due to the issue. With the patch applied, the NULL dereference was no longer observed through numerous resets.
