The Intel USBIO driver is x86 only, other architectures have ACPI so add an appropriate depenecy plus compile test.

2025-10-13dt-bindings: usb: switch: split out ports definitionNeil Armstrong
The ports definition currently defined in the usb-switch.yaml fits standards devices which are either recipient of altmode muxing and orientation switching events or an element of the USB Super Speed data lanes. This doesn't necessarely fit combo PHYs like the Qualcomm USB3/DP Combo which has a different ports representation. Move the ports definition to a separate usb-switch-ports.yaml and reference it next to the usb-switch.yaml, except for the Qualcomm USB3/DP Combo PHY bindings.

2025-10-13USB: Fix descriptor count when handling invalid MBIM extended descriptorSeungjin Bae
In cdc_parse_cdc_header(), the check for the USB_CDC_MBIM_EXTENDED_TYPE descriptor was using 'break' upon detecting an invalid length. This was incorrect because 'break' only exits the switch statement, causing the code to fall through to cnt++, thus incorrectly incrementing the count of parsed descriptors for a descriptor that was actually invalid and being discarded. This patch changes 'break' to 'goto next_desc;' to ensure that the logic skips the counter increment and correctly proceeds to the next descriptor in the buffer. This maintains an accurate count of only the successfully parsed descriptors.

2025-10-13ata: libata-core: relax checks in ata_read_log_directory()Damien Le Moal
Commit 6d4405b16d37 ("ata: libata-core: Cache the general purpose log directory") introduced caching of a device general purpose log directory to avoid repeated access to this log page during device scan. This change also added a check on this log page to verify that the log page version is 0x0001 as mandated by the ACS specifications. And it turns out that some devices do not bother reporting this version, instead reporting a version 0, resulting in error messages such as: ata6.00: Invalid log directory version 0x0000 and to the device being marked as not supporting the general purpose log directory log page. Since before commit 6d4405b16d37 the log page version check did not exist and things were still working correctly for these devices, relax ata_read_log_directory() version check and only warn about the invalid log page version number without disabling access to the log directory page.

2025-10-13usbip: Fix locking bug in RT-enabled kernelsLizhi Xu
Interrupts are disabled before entering usb_hcd_giveback_urb(). A spinlock_t becomes a sleeping lock on PREEMPT_RT, so it cannot be acquired with disabled interrupts. Save the interrupt status and restore it after usb_hcd_giveback_urb(). syz reported: BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48 Call Trace: dump_stack_lvl+0x189/0x250 lib/dump_stack.c:120 rt_spin_lock+0xc7/0x2c0 kernel/locking/spinlock_rt.c:57 spin_lock include/linux/spinlock_rt.h:44 [inline] mon_bus_complete drivers/usb/mon/mon_main.c:134 [inline] mon_complete+0x5c/0x200 drivers/usb/mon/mon_main.c:147 usbmon_urb_complete include/linux/usb/hcd.h:738 [inline] __usb_hcd_giveback_urb+0x254/0x5e0 drivers/usb/core/hcd.c:1647 vhci_urb_enqueue+0xb4f/0xe70 drivers/usb/usbip/vhci_hcd.c:818 Reported-by: syzbot+205ef33a3b636b4181fb@syzkaller.appspotmail.com Closes: https://syzkaller.appspot.com/bug?extid=205ef33a3b636b4181fb Signed-off-by: Lizhi Xu <lizhi.xu@windriver.com> Acked-by: Shuah Khan <skhan@linuxfoundation.org> Link: https://lore.kernel.org/r/20250916014143.1439759-1-lizhi.xu@windriver.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

The local variable 'res' is only used to temporary store the results of calling copy_from_user() and copy_to_user(). Use the results directly and remove the local variable.

2025-10-13usb: ehci: Add Aspeed AST2700 supportRyan Chen
Unlike earlier Aspeed SoCs (AST2400/2500/2600) which are limited to 32-bit DMA addressing, the EHCI controller in AST2700 supports 64-bit DMA. Update the EHCI platform driver to make use of this capability by selecting a 64-bit DMA mask when the "aspeed,ast2700-ehci" compatible is present in device tree.
