From 09ff7f1fc186c7c45211c8e70761863366e6c7b6 Mon Sep 17 00:00:00 2001 From: Lan Tianyu Date: Tue, 30 Jul 2013 14:00:42 +0200 Subject: ACPI / battery: Fix parsing _BIX return value commit 016d5baad04269e8559332df05f89bd95b52d6ad upstream. The _BIX method returns extended battery info as a package. According the ACPI spec (ACPI 5, Section 10.2.2.2), the first member of that package should be "Revision". However, the current ACPI battery driver treats the first member as "Power Unit" which should be the second member. This causes the result of _BIX return data parsing to be incorrect. Fix this by adding a new member called 'revision' to struct acpi_battery and adding the offsetof() information on it to extended_info_offsets[] as the first row.
