Subject: [PATCH v1 2/6] ACPI: glue: Change return type of two functions to void
Date: Mon, 12 Jul 2021 19:23:37 +0200	[thread overview]
Message-ID: <21118671.EfDdHjke4D@kreacher> (raw)
In-Reply-To: <2780027.e9J7NaK4W3@kreacher>

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

Since the return values of acpi_device_notify() and
acpi_device_notify_remove() are discarded by their only caller,
change their return type to void.

No functional impact.
