From 12866b99e57cf9eba809503c687fc1a25c529c4a Mon Sep 17 00:00:00 2001 From: Finn Thain Date: Wed, 23 Mar 2016 21:10:25 +1100 Subject: [PATCH] ncr5380: Fix register decoding for debugging Decode all bits in the chip registers. They are all useful at times. Fix printk severity so that this output can be suppressed along with the other debugging output.
