usb: fixes for v4.8-rc3
Few fixes on dwc3 again, the most important being a fix for pm_runtime to make it work with current intel platforms. Other than that, there's a signedness bug fix in fsl udc and some other minor fixes. -----BEGIN PGP SIGNATURE----- iQI6BAABCAAkBQJXvrw3HRxmZWxpcGUuYmFsYmlAbGludXguaW50ZWwuY29tAAoJ EIaOsuA1yqREWCMP/0zlF8sqCLgTOJcR8wBbzCCY6CLxrWrBxUB5+Ld6gs101f/0 d1YEqgRtGxauaJVdTfwiSoVTb+WGzG97ExHXBSQjcxniG/3u39Yq+KkKao6+Y4iR bqoT7vqPkLqNhVxzIL2Mx0uWBiCibl2NrAfXreNhSxHkabrf6JsWMfQ9Kc0N47/j aFRJ4U+NG/q53NbSfpfSxYG0p0LB4BHEpR0BVIKtWxMgFEsdwOMM6ZyqHpw3pede km7wqp/7HAUu2rhiZFQtLuPa7yjqlGEZ8vO1ERzIACDy+CiedRoJW+hHE0rJn4TL xjCLGEEeH7pP/lqAmsw6oxjg9cdhTakfMcM0374203U31hTIYC6PK1gRMivvE3rD zZ8RLU3NCuAh6HBQaHl/k+i3t9U76K/DJuFbSKnO1wwYMlDS2u6WBUWTXFDanYij BTIJSrqAEp+Ne3MCMQ0u79daTO5iTAhf08xbMwLJwY9c8k43bFmo2kYoGjo8aAyi 0U03NYMfuOTqcTpYNlRXyRhFGdCM0wxvYwzGaUs+oxPzzpsrQiotd0Lm8+UWSB/Y b4EfsZew0CBNnN3BPgyPDSrntPFiyL6OV2bRkLnxgUlwVEoEIBqTRu0Uv6bsrLkG qO4ibILgDbGUIuC8EyyR3ObQcTNQxxLTbdHyrNIq8dcgLypu3tW9jHHCe6vO =Tm2m -----END PGP SIGNATURE----- Merge tag 'fixes-for-v4.8-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus Felipe writes: usb: fixes for v4.8-rc3 Few fixes on dwc3 again, the most important being a fix for pm_runtime to make it work with current intel platforms.
