Message-ID: <38373412.2kgsblc99s@kreacher>
Date: Wed, 20 Jan 2021 19:59:05 +0100
From: "Rafael J. Wysocki" <rjw@...ysocki.net>

Subject: [PATCH v1 3/6] ACPI: bus: Clean up printing messages
From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
Replace all of the ACPI_DEBUG_PRINT() and ACPI_EXCEPTION() instances
in bus.c with pr_debug() and pr_info(), respectively, drop the
_COMPONENT and ACPI_MODULE_NAME() definitions that are not used any
more and replace direct printk() invocations with the matching
pr_*() calls (with a couple of exceptions where the log level is
decreased).
