Title
drm/amdgpu: Fix runtime PM leak in amdgpu_debugfs_test_ib_show()
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix runtime PM leak in amdgpu_debugfs_test_ib_show() amdgpu_debugfs_test_ib_show() resumes the device with pm_runtime_get_sync() before taking the reset domain semaphore with down_write_killable(). If the write lock acquisition is interrupted, the function returns without calling pm_runtime_put_autosuspend(), leaking the runtime PM reference acquired for the device and keeping the GPU awake. Drop the runtime PM reference on the interrupted down_write_killable() error path before returning. (cherry picked from commit ec30a576c2d4c0364549e6c04218f50704ef56c8)
