From b56ca501a4112b568102e6f910ed3d5e32dde52c Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Thu, 16 Dec 2021 11:08:07 -0800 Subject: [PATCH] spmi: pmic-arb: Add sid and address to error messages It's useful to know what particular device/component is having trouble accessing the bus. Add the sid and address to error messages here so that debugging is a little simpler.
