From 0986b16ab49b18063d29a9e02e9c7fab1928bc8e Mon Sep 17 00:00:00 2001 From: Finn Thain Date: Fri, 24 Aug 2018 12:02:06 +1000 Subject: m68k/mac: Use correct PMU response format Now that the 68k Mac port has adopted the via-pmu driver, it must decode the PMU response accordingly otherwise the date and time will be wrong.
