usb: cdnsp: Fixes error: uninitialized symbol 'len'

The patch 5bc38d33a5a1: "usb: cdnsp: Fixes issue with redundant Status Stage" leads to the following Smatch static checker warning: drivers/usb/cdns3/cdnsp-ep0.c:470 cdnsp_setup_analyze() error: uninitialized symbol 'len'. cc: Fixes: 5bc38d33a5a1 ("usb: cdnsp: Fixes issue with redundant Status Stage") Signed-off-by: Pawel Laszczak Link: https://lore.kernel.org/r/20230331090600.454674-1-pawell@cadence.com Signed-off-by: Greg Kroah-Hartman

usb: gadgetfs: Fix ep_read_iter to handle ITER_UBUF

2023-04-05T17:24:01Z

iov_iter for ep_read_iter can be ITER_UBUF with io_uring. In that case dup_iter() does not have to allocate iov and it can return NULL. Fix the assumption by checking for iter_is_ubuf() other wise ep_read_iter can treat this as failure and return -ENOMEM.

iov_iter for ffs_epfile_read_iter can be ITER_UBUF with io_uring. In that case dup_iter() does not have to allocate anything and it can return NULL. ffs_epfile_read_iter treats this as a failure and returns -ENOMEM. Fix it by checking if iter_is_ubuf().

usb: typec: altmodes/displayport: Fix configure initial pin assignment

2023-04-05T17:20:12Z

While determining the initial pin assignment to be sent in the configure message, using the DP_PIN_ASSIGN_DP_ONLY_MASK mask causes the DFP_U to send both Pin Assignment C and E when both are supported by the DFP_U and UFP_U. The spec (Table 5-7 DFP_U Pin Assignment Selection Mandates, VESA DisplayPort Alt Mode Standard v2.0) indicates that the DFP_U never selects Pin Assignment E when Pin Assignment C is offered. Update the DP_PIN_ASSIGN_DP_ONLY_MASK conditional to intially select only Pin Assignment C if it is available.

xhci: Free the command allocated for setting LPM if we return early

2023-03-30T14:42:17Z

The command allocated to set exit latency LPM values need to be freed in case the command is never queued. This would be the case if there is no change in exit latency values, or device is missing.

Revert "usb: xhci-pci: Set PROBE_PREFER_ASYNCHRONOUS"

2023-03-30T14:42:02Z

This reverts commit 4c2604a9a6899bab195edbee35fc8d64ce1444aa. Asynch probe caused regression in a setup with both Renesas and Intel xHC controllers. Devices connected to the Renesas disconnected shortly after boot. With Asynch probe the busnumbers got interleaved. xhci_hcd 0000:00:14.0: new USB bus registered, assigned bus number 1 xhci_hcd 0000:04:00.0: new USB bus registered, assigned bus number 2 xhci_hcd 0000:00:14.0: new USB bus registered, assigned bus number 3 xhci_hcd 0000:04:00.0: new USB bus registered, assigned bus number 4 Reason why this commit causes regression is still unknown, but revert it while debugging the issue.

xhci: also avoid the XHCI_ZERO_64B_REGS quirk with a passthrough iommu

2023-03-30T14:41:58Z

Previously the quirk was skipped when no iommu was present. The same rationale for skipping the quirk also applies in the iommu.passthrough=1 case. Skip applying the XHCI_ZERO_64B_REGS quirk if the device's iommu domain is passthrough.
