From mboxrd@z Thu Jan 1 00:00:00 1970 From: =?UTF-8?q?Micha=C5=82=20K=C4=99pie=C5=84?= Subject: [PATCH 6/7] platform/x86: fujitsu-laptop: do not evaluate ACPI _INI methods Date: Fri, 16 Jun 2017 06:40:57 +0200 Message-ID: <20170616044058.30443-7-kernel@kempniu.pl> References: <20170616044058.30443-1-kernel@kempniu.pl> Mime-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Return-path: In-Reply-To: <20170616044058.30443-1-kernel@kempniu.pl> Sender: linux-kernel-owner@vger.kernel.org To: Jonathan Woithe , Darren Hart , Andy Shevchenko Cc: platform-driver-x86@vger.kernel.org, linux-acpi@vger.kernel.org, linux-kernel@vger.kernel.org List-Id: linux-acpi@vger.kernel.org acpi_ns_initialize_devices(), which is called during system-wide ACPI initialization, already detects and calls all _INI methods belonging to objects present in ACPI tables. There is no need to call these methods again every time the module is loaded because they only initialize status flags and hotkey-related variables; status flags are effectively constants, hotkey-related variables may be assigned non-zero values before acpi_fujitsu_laptop_add() is called, but that does not really matter as we drain the scancodes queued in the firmware's ring buffer before doing anything else. Remove sections of code which invoke and check evaluation status of the _INI methods belonging to the ACPI devices handled by the driver.
