From ce47d531c33c35eca985f2dffc340c09433690fa Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Wed, 21 Jun 2023 09:53:52 +0100 Subject: [PATCH] mac_via: fix rtc command decoding from PRAM addresses 0x0 to 0xf A comparison between the rtc command table included in the comment and the code itself shows that the decoding for PRAM addresses 0x0 to 0xf is being done on the raw command, and not the shifted version held in value.
