Subject: [PATCH v2 6/8] ACPI: PM: s2idle: Eliminate acpi_sleep_no_ec_events()
Date: Tue, 30 Jul 2019 12:01:44 +0200	[thread overview]
Message-ID: <25240910.MlnzASiNL0@kreacher> (raw)
In-Reply-To: <7528887.mqcfy9PZua@kreacher>

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Change acpi_ec_suspend() to use pm_suspend_no_platform() instead of
acpi_sleep_no_ec_events(), which allows the latter to be eliminated
along with the s2idle_in_progress variable which is only used by it.

Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

New in v2.
