+Subject: [PATCH 3390/4131] drm/amdkfd: fix amdkfd use-after-free GP fault
+
+Fix GP fault caused by dev_info() reference to a struct device*
+after the device has been freed (use after free).
+kfd_chardev_exit() frees the device so 'kfd_device' should not
+be used after calling kfd_chardev_exit().
