Subject: [PATCH] ACPI / bus: Use acpi_handle_debug() in acpi_print_osc_error()

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

acpi_print_osc_error() basically duplicates the functionalit of
acpi_handle_debug(), so use that one in there.

While at it, convert the explicit KERN_DEBUG prints to pr_debug()
(and apply it to continuation messages too).
