From fce96f3e5d34b0e3195f9d1bf2b3c7e3841e90ff Mon Sep 17 00:00:00 2001 From: Willy Tarreau Date: Fri, 18 Sep 2009 22:45:47 +0200 Subject: [PATCH] i2c/scx200_acb: Provide more information on bus errors Upon a bus error, it's rather hard to guess what happened. Dumping the address, length and status provides a lot of value for troubleshooting issues.
