CVE-2026-43072

Description

In the Linux kernel, the following vulnerability has been resolved: drm/vc4: platform_get_irq_byname() returns an int platform_get_irq_byname() will return a negative value if an error happens, so it should be checked and not just passed directly into devm_request_threaded_irq() hoping all will be ok.
