Rob Clark 8103d53f25 drm/msm/gpu: Fix potential double-free ... [ Upstream commit a66f1efcf7 ] If userspace was calling the MSM_SET_PARAM ioctl on multiple threads to set the COMM or CMDLINE param, it could trigger a race causing the previous value to be kfree'd multiple times. Fix this by serializing on the gpu lock.
