Subject: [PATCH] iio: adc: pac1921: add missing error return in probe()
Date: Thu, 8 Aug 2024 22:28:17 +0300	[thread overview]
Message-ID: <1fa4ab12-0939-477d-bc92-306fd32e4fd9@stanley.mountain> (raw)

This error path was intended to return, and not just print an error.  The
current code will lead to an error pointer dereference.

Fixes: 371f778b83cd ("iio: adc: add support for pac1921")
Signed-off-by: Dan Carpenter <dan.carpenter@linaro.org>
