Subject: [PATCH v1 1/6] ACPI: power: Clean up printing messages
Date: Wed, 20 Jan 2021 19:57:03 +0100 [thread overview]
Message-ID: <2085818.bEvWYRANqJ@kreacher> (raw)
In-Reply-To: <2809410.8bz27usjlQ@kreacher>
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Replace all of the ACPI_DEBUG_PRINT() instances in power.c with
acpi_handle_debug() or pr_debug(), depending on the context,
drop the _COMPONENT and ACPI_MODULE_NAME() definitions that
are not used any more, and replace the direct invocations of
printk() in there with acpi_handle_info() or pr_info(), depending
on the context.
