Message-ID: <5760611.lOV4Wx5bFT@iron-maiden>
Date: Fri, 09 Jul 2021 09:38:44 -0400
From: Carlos Bilbao <bilbao@...edu>
To: James.Bottomley@...senpartnership.com

Subject: [PATCH] drivers: parisc: Update iosapic driver with proper printks
The code from the old I/O Sapic Driver is outdated when it comes to printks.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.
