Subject: [PATCH v1 2/2] ACPI: OSL: Clean up printing messages
Date:   Mon, 08 Feb 2021 19:59:57 +0100

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Replace the ACPI_DEBUG_PRINT() instance in osl.c unrelated to the
ACPICA debug with acpi_handle_debug(), add a pr_fmt() definition
to osl.c and replace direct printk() usage in that file with the
suitable pr_*() calls.

While at it, add a physical address value to the message in
acpi_os_map_iomem() and reword a couple of messages to avoid
using function names in them.
