Fix error path handling in rocket_job_run()","description":"In the Linux kernel, the following vulnerability has been resolved:\n\naccel/rocket: Fix error path handling in rocket_job_run()\n\nIn rocket_job_run(), after taking an extra fence reference for\njob->done_fence via dma_fence_get(), the error paths have three bugs:\n\n- The dma_fence reference held by job->done_fence is never released,\n  causing a reference leak.\n- pm_runtime_get_sync() increments the usage counter even on failure,\n  but the error path does not decrement it, leaking the runtime PM\n  reference and preventing the NPU from suspending.\n- A valid but unsignaled fence is returned to the DRM scheduler,\n  which triggers WARN(\"Fence ... released with pending signals!\")\n  when the scheduler drops its reference.\n\nFix by replacing pm_runtime_get_sync() with pm_runtime_resume_and_get()\nwhich auto-balances the usage counter on failure, releasing both fence\nreferences on error, and returning ERR_PTR(ret) instead of the\nunsignaled fence.\n\n[tomeu: Refactored error paths to use consolidated goto
