Subject: [PATCH 05/16] ASoC: cs42l42: Defer probe if request_threaded_irq() returns EPROBE_DEFER
Date: Fri, 15 Oct 2021 14:36:08 +0100 [thread overview]
Message-ID: <20211015133619.4698-6-rf@opensource.cirrus.com> (raw)
In-Reply-To: <20211015133619.4698-1-rf@opensource.cirrus.com>
The driver can run without an interrupt so if devm_request_threaded_irq()
failed, the probe() just carried on. But if this was EPROBE_DEFER the
driver would continue without an interrupt instead of deferring to wait
for the interrupt to become available.
Fixes: 2c394ca79604 ("ASoC: Add support for CS42L42 codec")
