From c105aa31183a6ebec395681b6df47c8b65259322 Mon Sep 17 00:00:00 2001 From: Juri Lelli Date: Wed, 31 May 2017 17:59:29 +0100 Subject: arm,arm64,drivers: reduce scope of cap_parsing_failed Reduce the scope of cap_parsing_failed (making it static in drivers/base/arch_topology.c) by slightly changing {arm,arm64} DT parsing code. For arm checking for !cap_parsing_failed before calling normalize_ cpu_capacity() is superfluous, as returning an error from parse_ cpu_capacity() (above) means cap_from _dt is set to false. For arm64 we can simply check if raw_capacity points to something, which is not if capacity parsing has failed.
