Hello.
Here is a set of patches coming up from a report of Dan Carpenter about some
buffers in atusb are on the stack and that produces a problem with DMA from 4.9
onwards.
The first patch covers existing code present in released 4.9. I added a stable
tag for it to make sure it gets into the stable updates. Marcel, I also checked
that this patch applies cleanly against bluetooth.git as well as bluetooth-next.git.
The second patch just handles a corner case a bit more cleanly and the third ones
fixes the buffer on a stack problem for code introduced in the 4.10 merge window
and should got.
Thanks to Dan for reporting this.
