Subject: [PATCH v1 2/2] ACPI: OSL: Clean up printing messages

From: Rafael J. Wysocki <[email protected]>

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.

If you do more of these, perhaps rewrap lines to 80 columns when possible.

pr_info("Overriding _OS definition to '%s'\n", acpi_os_name);

etc...

I've overlooked this one, will fix it up in the final commit.

Thanks!
