Subject: [PATCH] iio: adc: pac1934: Return -ENOMEM on memory allocation failure
Date: Wed, 11 Feb 2026 19:10:05 +0200 [thread overview]
Message-ID: <20260211171007.143527-1-antoniu.miclaus@analog.com> (raw)
devm_kzalloc() returns NULL on allocation failure. The appropriate error
code for this condition is -ENOMEM, not -EINVAL.
Fixes: 0fb528c8255b ("iio: adc: adding support for PAC193x")
