Specifically, drivers which took care not modify the runtime-PM usage counter after their disconnect callback had returned, would now fail to be suspended when a driver is later bound. Greg, feel free to pick these up directly. The media patch has been acked by Mauro. Johan v2 - rebase on usb-next, I had a conflicting change to usb-skeleton in my tree - add Mauro's ack to the media patch Johan Hovold (4): USB: usb-skeleton: fix runtime PM after driver unbind USB: usblp: fix runtime PM after driver unbind USB: serial: fix runtime PM after driver unbind media: stkwebcam: fix runtime PM after driver unbind drivers/media/usb/stkwebcam/stk-webcam.c | 3 +-- drivers/usb/class/usblp.c | 8 +++++--- drivers/usb/serial/usb-serial.c | 5 +---- drivers/usb/usb-skeleton.c | 8 +++----- 4 files changed, 10 insertions(+), 14 deletions(-)
