drm/nouveau/pmu: do not assume a PMU is present

2016-02-19T22:28:38+00:00

commit 579b7c58215329803ce184704463de09f0f310ac upstream. Some devices may not have a PMU. Avoid a NULL pointer dereference in such cases by checking whether the pointer given to nvkm_pmu_pgob() is valid. Signed-off-by: Alexandre Courbot Signed-off-by: Ben Skeggs Signed-off-by: Greg Kroah-Hartman

2015-10-31T00:00:05+00:00

The size here comes from the user via the ioctl, it is a number between 1-u32max so the addition here could overflow on 32 bit systems.
