From d5ff18bcd4b5e66396eab7e8271172157ee1253e Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Thu, 11 Jan 2018 11:12:41 +0000 Subject: [PATCH] IIO: ADC: fix return value check in stm32_dfsdm_adc_probe() In case of error, the function devm_iio_device_alloc() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test.
