Subject: [PATCH] ACPI: dock: use dynamically allocated platform device
Date: Wed, 9 May 2007 15:07:04 -0700 [thread overview]
Message-ID: <20070509150704.64e454ab.kristen.c.accardi@intel.com> (raw)
ACPI: dock: use dynamically allocated platform device
Get rid of no release function warnings by switching to dynamically
allocating the platform_device and using the platform device release
routine in the base driver.
