Subject: [PATCH] pwm: jz4740: Don't use dev_err_probe() in .request()
Date: Sat,  6 Jan 2024 15:13:03 +0100	[thread overview]
Message-ID: <20240106141302.1253365-2-u.kleine-koenig@pengutronix.de> (raw)

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()").
