In the Linux kernel, the following vulnerability has been resolved:
drm/msm/a6xx: Avoid a nullptr dereference when speedbin setting fails
Calling a6xx_destroy() before adreno_gpu_init() leads to a null pointer
dereference on:
msm_gpu_cleanup() : platform_set_drvdata(gpu->pdev, NULL);
as gpu->pdev is only assigned in:
a6xx_gpu_init()
|_ adreno_gpu_init
|_ msm_gpu_init()
Instead of relying on handwavy null checks down the cleanup chain,
explicitly de-allocate the LLC data and free a6xx_gpu instead.
