Pull SCSI updates from James Bottomley: "Only ufs driver updates this time, apart from which this is just an assortment of bug fixes and AI assisted changes. The biggest other change is the reversion of the sas_user_scan patch which supported a mpi3mr NVME behaviour but caused major issues for other sas controllers.

scsi: ufs: ufs-qcom: Enable Auto Hibern8 clock request support

2026-05-15T02:19:08+00:00

On platforms that support Auto Hibern8 (AH8), the UFS controller can autonomously de-assert clk_req signals to the Global Clock Controller when entering the Hibern8 state. This allows Global Clock Controller (GCC) to gate unused clocks, improving power efficiency. Enable the Clock Request feature by setting the UFS_HW_CLK_CTRL_EN bit in the UFS_AH8_CFG register, as recommended in the Hardware Programming Guidelines.

scsi: ufs: ufshcd-pci: Use PCI_VDEVICE and named initializers for pci array

2026-05-15T01:39:23+00:00

The pci_device_id array uses a mixture of ways to initialize ufshcd_pci_tbl[]. List initializers are hard to read unless you memoized the order of the struct members. Use the PCI_VDEVICE for all entries and a named initializer for .driver_data. This allows to idiomatically assign the members without using zeros to fill the fields before .driver_data (either explicitly or hidding in PCI_VDEVICE()). There are no changes to the compiled result of the array; verified with builds for x86 and arm64.

scsi: ufs: tc-dwc-g210-pci: Simplify initialization of pci_device_id array

2026-05-15T01:39:23+00:00

A list initializer is hard to parse for a human if they don't see or know the order of the members of struct pci_device_id. So use the PCI_VDEVICE macro which is much more idiomatic and skip assigning explicit zeros. There are no changes to the compiled result of the array; verified with builds for x86 and arm64.
