Subject: [PATCH] spmi: pmic-arb: Add sid and address to error messages
Date: Mon, 20 Sep 2021 16:48:49 -0700	[thread overview]
Message-ID: <20210920234849.3614036-1-swboyd@chromium.org> (raw)

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.
