Subject: [PATCH 2/3] ACPI / bind: Pass struct acpi_device pointer to acpi_bind_one()
Date: Fri, 29 Nov 2013 01:38:15 +0100 [thread overview]
Message-ID: <10690501.mTAEnhY36F@vostro.rjw.lan> (raw)
In-Reply-To: <4501334.ovACrGogrl@vostro.rjw.lan>
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
There is no reason to pass an ACPI handle to acpi_bind_one() instead
of a struct acpi_device pointer to the target device object, so
modify that function to take a struct acpi_device pointer as its
second argument and update all code depending on it accordingly.
