Subject: PCI PM & compatibility
Date: Sat, 23 Aug 2003 16:39:57 +0200 [thread overview]
Message-ID: <1061649597.780.4.camel@gaston> (raw)
Hi !
What about this patch to stay compatible with existing drivers
implementing everything in save_state ?
Ideally, we should kill save_state and fix all drivers, oh well...
(This version of the patch has correct space/tabs)
Ben.
