Hi, I applied this series to extcon-testing branch. If there are no build problem for few days, I'll move them to extcon-next branch.

Thanks.

So Acked-by: Linus Walleij <linus.walleij@linaro.org> This driver I see is already sent to Greg for inclusion in the next kernel. I just wonder if you guys are even aware of this driver for the same hardware added by Donggeun Kim in 2011: drivers/misc/fsa9480.c That said I am all for pulling in this new driver because it is surely better and supports device tree. But can we please also send Greg a patch to delete the old driver so we don't have two of them now? The old driver have no in-tree users so it can be deleted without side effects. Out-of-tree users can certainly adapt to the new extcon driver. If you want I can send a deletion patch for the misc driver? Yours, Linus Walleij

Please, I'll gladly take a patch that deletes code :) thanks, greg k-h

If You could do this (and maybe it'll get merged faster) i'll be great. Thanks > > Please, I'll gladly take a patch that deletes code :)If You ca > > thanks, > > greg k-h
