5.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx> commit 9320fc509b87b4d795fb37112931e2f4f8b5c55f upstream. dev_err_probe() is only supposed to be used in probe functions. While it probably doesn't hurt, both the EPROBE_DEFER handling and calling device_set_deferred_probe_reason() are conceptually wrong in the request callback. So replace the call by dev_err() and a separate return statement. This effectively reverts commit c0bfe9606e03 ("pwm: jz4740: Simplify with dev_err_probe()").
