This happens when the xHCI driver enqueue a control TD (which cross over the Link TRB between two ring segments, as shown) in the endpoint zero's transfer ring. Seems the Etron xHCI host can not perform this TD correctly, causing the USB transfer error occurred, maybe the upper driver retry that control-IN request can solve problem, but not all drivers do this. | | ------- | TRB | Setup Stage ------- | TRB | Link ------- ------- | TRB | Data Stage ------- | TRB | Status Stage ------- | | To work around this, the xHCI driver should enqueue a No Op TRB if next available TRB is the Link TRB in the ring segment, this can prevent the Setup and Data Stage TRB to be breaked by the Link TRB. Check if the XHCI_ETRON_HOST quirk flag is set before invoking the workaround in xhci_queue_ctrl_tx(). Fixes: d0e96f5a71a0 ("USB: xhci: Control transfer support.")

[PATCH] ALSA: usb-audio: Add extra PID for RME Digiface USB

by Asahi Lina

It seems there is an alternate version of the hardware with a different PID. User testing reveals this still works with the same interface as far as the kernel is concerned, so just add the extra PID. Thanks to Heiko Engemann for testing with this version. Due to the way quirks-table.h is structured, that means we have to turn the entire quirk struct into a macro to avoid duplicating it...

[PATCH] mmc: core: Further prevent card detect during shutdown

by Ulf Hansson

Disabling card detect from the host's ->shutdown_pre() callback turned out to not be the complete solution. More precisely, beyond the point when the mmc_bus->shutdown() has been called, to gracefully power off the card, we need to prevent card detect. Otherwise the mmc_rescan work may poll for the card with a CMD13, to see if it's still alive, which then will fail and hang as the card has already been powered off. To fix this problem, let's disable mmc_rescan prior to power off the card during shutdown.
