Subject: [PATCH v2 1/5] ACPI: AC: Clean up printing messages

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

Replace the ACPI_DEBUG_PRINT() and ACPI_EXCEPTION() instances
in ac.c with acpi_handle_debug() and acpi_handle_info() calls,
respectively, which among other things causes the excessive log
level of the messages previously printed via ACPI_EXCEPTION() to
be more adequate.

Drop the _COMPONENT and ACPI_MODULE_NAME() definitions that are not
used any more, drop the no longer needed ACPI_AC_COMPONENT definition
from the headers and update the documentation accordingly.

In this file, printk() is still using, how about convert them
all into pr_*? I think patch on top your or update this patch
are both OK.

Thanks

Good idea.

Thanks for all of the comments. They will be addressed in the v3 that will be
posted shortly.
