Subject: [PATCH -next] ASoC: samsung: i2s: Fix return value check in i2s_create_secondary_device()
Date: Sat, 16 Feb 2019 01:20:55 +0000 [thread overview]
Message-ID: <20190216012055.79622-1-weiyongjun1@huawei.com> (raw)
In case of error, the function platform_device_register_simple() returns
ERR_PTR() and never returns NULL. The NULL test in the return value
check should be replaced with IS_ERR().
Fixes: 7196c64c7d0c ("ASoC: samsung: i2s: Restore support for the secondary PCM")
