[PATCH] pm_message_t corrections still missing from 2.6.12-rc2

From: Nigel Cunningham
Date: Fri Apr 08 2005 - 07:07:40 EST


Hi.

Here, for your consideration, are fixups I still have in my tree after
updating to rc2.

(USB & Framebuffer lists copied because a reasonable number apply
there).

Regards,

Nigel
