The driver_override field from platform driver should not be initialized from static memory (string literal) because the core later kfree() it, for example when driver_override is set via sysfs.
Use dedicated helper to set driver_override properly.

See my comment to patch 01/11.
I would like this to look like the following:
ret = driver_set_override(&pdev->dev, "imx-scu-clk");
- if (ret) {
platform_device_put(pdev);
return ERR_PTR(ret);
- }
ret = imx_clk_scu_attach_pd(&pdev->dev, rsrc_id); if (ret) -- 2.32.0
