From: Rafael J. Wysocki <[email protected]>
Replace the ACPI_DEBUG_PRINT() and ACPI_EXCEPTION() instances
in battery.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_BATTERY_COMPONENT
definition from the headers and update the documentation accordingly.
While at it, update the pr_fmt() definition and drop the unneeded
PREFIX sybmbol definition from battery.c.

Will print:
ACPI: battery: Battery Slot ...
How about:
ACPI: battery: Slot ...

Will print:
ACPI: battery: Battery: found native...
will be better for
ACPI: battery: found native
So I think we can remove ACPI_BATTERY_DEVICE_NAME in pr_info()
Thanks
