Message-Id: <20170424133334.7064-4-kernel@kempniu.pl>
Date: Mon, 24 Apr 2017 15:33:27 +0200
From: Michał Kępień <kernel@...pniu.pl>
To: Jonathan Woithe <jwoithe@...t42.net>,

Cc: platform-driver-x86@...r.kernel.org, linux-kernel@...r.kernel.org
Subject: [PATCH 03/10] platform/x86: fujitsu-laptop: explicitly pass ACPI handle to call_fext_func()
Prepare for not using module-wide data in call_fext_func() by explicitly
passing it an ACPI handle to the FUJ02E3 device while still using the
module-wide handle in each call to fext_*() helper functions.
