[PATCH v1 1/4] ACPI: PCI: IRQ: Consolidate printing diagnostic messages

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>

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.
