[PATCH v1 3/6] ACPI: bus: Clean up printing messages
From: Rafael J. Wysocki
Date: Wed Jan 20 2021 - 14:11:57 EST
From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>
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).
