ACPI: AC: Clean up printing messages
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 increased. 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. While at it, replace the direct printk() invocation with pr_info(), add a pr_fmt() definition to ac.c and drop the unneeded PREFIX symbol definition from there. Signed-off-by: Rafael J.
