Wysocki The code in pci_irq.c prints diagnostic messages using different and inconsistent methods. The majority of them are printed with the help of the dev_*() familiy of logging functions, but ACPI_DEBUG_PRINT() and ACPI_DEBUG_PRINT_RAW() are still used in some places which requires the ACPICA debug to be enabled additionally which is a nuisance and one message is printed using the raw printk(). To consolidate the printing of messages in that code, convert all of the ACPI_DEBUG_PRINT() instances in it into dev_dbg(), which is consistent with the way the other messages are printed by it, replace the only ACPI_DEBUG_PRINT_RAW() instance with pr_debug() and make it use pr_warn() istead of printk(KERN_WARNING ). Also add a pr_fmt() definition to that file and drop the _COMPONENT and ACPI_MODULE_NAME() definitions that are not used any more after the above changes. Signed-off-by: Rafael J.
