We've had this bug for a long time, loosing the key release packets most of the time, which did not matter, until my recent usb-kbd keyrepeat changes. The first patch in this series fixes this, the second patch is a better safe then sorry patch I wrote while working on this. Can you please queue both of these up for merging into v2015.07 ? Applied both, thanks! Best regards, Marek Vasut ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
