I don't want to force it into 6.13/usb-linus at this stage over the holidays. Adding it to 6.14/usb-next and stable should be fine. Thanks Mathias Mathias Nyman (4): xhci: dbc: Improve performance by removing delay in transfer event polling. xhci: dbgtty: Improve performance by handling received data immediately. xhci: Add command completion parameter support xhci: Add missing capability definition bits Michal Pecio (1): usb: xhci: Fix NULL pointer dereference on certain command aborts drivers/usb/host/xhci-caps.h | 6 +++ drivers/usb/host/xhci-dbgcap.c | 2 +- drivers/usb/host/xhci-dbgtty.c | 98 ++++++++++++++++++++++------------ drivers/usb/host/xhci-ring.c | 13 +++-- drivers/usb/host/xhci.h | 4 ++ 5 files changed, 84 insertions(+), 39 deletions(-)
