In the general case, the resources are properly released by devm without
needing to do anything. However, when unplugging the wireless receiver,
the kernel segfaults from time to time while calling devres_release_all().
I think in that case the resources attempt to access hid_get_drvdata(hdev)
which has been set to null while leaving wacom_remove().
