Subject: [PATCH] drivers: parisc: Update sba_iommu driver with proper printks
Date:   Fri, 09 Jul 2021 09:45:45 -0400
Message-ID: <4359868.LvFx2qVVIh@iron-maiden>

Precedence: bulk

The code from the old SBA IOMMU manager is outdated when it comes to printks. 
Fix applying proper indentation and using dev_dbg() instead of printk on 
debugging blocks. Also add a KERN_<LEVEL> where it is missing.
