Subject: [PATCH v3 6/8] ACPI: EC: PM: Consolidate some code depending on PM_SLEEP
Date: Fri, 02 Aug 2019 12:43:08 +0200 [thread overview]
Message-ID: <2097262.dE6Kv6hMgP@kreacher> (raw)
In-Reply-To: <5997740.FPbUVk04hV@kreacher>
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Move some routines, including acpi_ec_dispatch_gpe(), that are only
used if CONFIG_PM_SLEEP is set to the #ifdef block containing the EC
suspend and resume callbacks, to make the "full EC PM picture" easier
to follow.
While at it, move the header of acpi_ec_dispatch_gpe() in the
header file to a CONFIG_PM_SLEEP #ifdef block.
Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

In v2 this was patch 7.
