Subject: [PATCH] Power: call save_state on PCI devices along with suspend
Date: Tue, 09 Sep 2003 20:41:42 +0200 [thread overview]
Message-ID: <1063132902.1356.17.camel@gaston> (raw)
Hi Patrick !
Don't we want that ? It will help if any driver currently relies on
the save_state callback to be called...
Ben.
