Greg / Rafael: any thoughts on this patch? Care to give it an Ack so it could go through the Qualcomm tree? Andrew: I think you are the adopter or orphan patches, usually. If nobody else will take this patch, will you consider taking it into your tree? It should be a super straightforward bugfix. I'm happy to re-post it CCing you if need be. Thanks! -Doug
