From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx> A few x86 platform drivers use ACPI_DEBUG_PRINT() or ACPI_EXCEPTION() for printing messages, but that is questionable, because those macros belong to ACPICA and they should not be used elsewhere. In addition, ACPI_DEBUG_PRINT() requires special enabling to allow it to actually print the message, which is a nuisance, and the _COMPONENT symbol generally needed for that is not defined in any of the files in question. For this reason, replace the ACPI_DEBUG_PRINT() in lg-laptop.c with pr_debug() and the one in xo15-ebook.c with acpi_handle_debug() (with the additional benefit that the source object can be identified more easily after this change), and replace the ACPI_EXCEPTION() in acer-wmi.c with pr_warn(). Also drop the ACPI_MODULE_NAME() definitions that are only used by the ACPICA message printing macros from those files and from wmi.c and surfacepro3_button.c (while at it). Signed-off-by: Rafael J.
