From 636458de36f1fb4cdd318387d2f45604e451b17a Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Fri, 21 Dec 2012 00:36:47 +0100 Subject: ACPI: Remove the arguments of acpi_bus_add() that are not used Notice that acpi_bus_add() uses only 2 of its 4 arguments and redefine its header to match the body. Update all of its callers as necessary and observe that this leads to quite a number of removed lines of code (Linus will like that). Add a kerneldoc comment documenting acpi_bus_add() and wonder how its callers make wrong assumptions about the second argument (make note to self to take care of that later). Signed-off-by: Rafael J.
