[PATCH] iommu/fsl-pamu: Fix uninitialized variable warning

From: Joerg Roedel
Date: Thu Apr 15 2021 - 10:44:49 EST


From: Joerg Roedel <jroedel@xxxxxxx>

The variable 'i' in the function update_liodn_stash() is not
initialized and only used in a debug printk(). So it has no
meaning at all, remove it.
