GHSA-c6q3-q7pq-58wm 
In the Linux kernel, the following vulnerability has been resolved:drm/msm: don't free the IRQ if it was not requestedAs msm_drm_uninit() is called from the msm_drm_init() error path,
additional care should be necessary as not to call the free_irq() for
the IRQ that was not requested before (because an error occured earlier
than the request_irq() call).This fixed the issue reported with the following backtrace:[    8.571329] Trying to free already-free IRQ 187
