Subject: iommu/pamu: Use kzfree() in fsl_pamu_probe()
X-Git-Tag: v5.9-rc1~60^2~1^8
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f5e383ac8b58f421ac0a005f6df4f2e9eefeb93f;p=thirdparty%2Fkernel%2Flinux.git

iommu/pamu: Use kzfree() in fsl_pamu_probe()

Use kzfree() instead of opencoded memset with 0 followed by kfree().
Null check is not required since kzfree() checks for NULL internally.
