Subject: [PATCH] iommu: fsl_pamu: use kzfree() in fsl_pamu_probe()
Date: Thu, 4 Jun 2020 15:37:09 +0300 [thread overview]
Message-ID: <20200604123709.96561-1-efremov@linux.com> (raw)
Use kzfree() instead of opencoded memset with 0 followed by kfree().
Null check is not required since kzfree() checks for NULL internally.
