Return NOTIFY_DONE (dont't care) for switchdev notifications that prestera driver don't know how to handle them. With introduction of SWITCHDEV_BRPORT_[UN]OFFLOADED switchdev events, the driver rejects adding swport to bridge operation which is handled by prestera_bridge_port_join() func. The root cause of this is that prestera driver returns error (EOPNOTSUPP) in prestera_switchdev_blk_event() handler for unknown swdev events. This causes switchdev_bridge_port_offload() to fail when adding port to bridge in prestera_bridge_port_join().

2021-11-19drm/aspeed: Fix vga_pw sysfs outputJoel Stanley1-1/+1
Before the drm driver had support for this file there was a driver that exposed the contents of the vga password register to userspace. It would present the entire register instead of interpreting it. The drm implementation chose to mask of the lower bit, without explaining why. This breaks the existing userspace, which is looking for 0xa8 in the lower byte. Change our implementation to expose the entire register.

2021-11-18scsi: target: configfs: Delete unnecessary checks for NULLDan Carpenter1-8/+8
The "item" pointer is always going to be valid pointer and does not need to be checked. But if "item" were NULL then item_to_lun() would not return a NULL, but instead, the container_of() pointer math would return a value in the error pointer range. This confuses static checkers since it looks like a NULL vs IS_ERR() bug. Delete the bogus checks.

For updating the IOC firmware's timestamp with system timestamp, the driver issues the Mpi26IoUnitControlRequest message. While framing the Mpi26IoUnitControlRequest, the driver should copy the lower 32 bits of the current timestamp into IOCParameterValue field and the higher 32 bits into Reserved7 field.

2021-11-18scsi: mpt3sas: Fix system going into read-only modeSreekanth Reddy2-1/+60
While determining the SAS address of a drive, the driver checks whether the handle number is less than the HBA phy count or not. If the handle number is less than the HBA phy count then driver assumes that this handle belongs to HBA and hence it assigns the HBA SAS address. During IOC firmware downgrade operation, if the number of HBA phys is reduced and the OS drive's device handle drops below the phy count while determining the drive's SAS address, the driver ends up using the HBA's SAS address. This leads to a mismatch of drive's SAS address and hence the driver unregisters the OS drive and the system goes into read-only mode. Update the IOC's num_phys to the HBA phy count provided by actual loaded firmware.

If lp->active is 8 and the second comparison of this macro is false. lp->active will remain 8 in: lp->phy[lp->active].gep = (*p ? p : NULL); p += (2 * (*p) + 1); lp->phy[lp->active].rst = (*p ? p : NULL); p += (2 * (*p) + 1); lp->phy[lp->active].mc = get_unaligned_le16(p); p += 2; lp->phy[lp->active].ana = get_unaligned_le16(p); p += 2; lp->phy[lp->active].fdx = get_unaligned_le16(p); p += 2; lp->phy[lp->active].ttm = get_unaligned_le16(p); p += 2; lp->phy[lp->active].mci = *p; However, the length of array lp->phy is 8, so array overflows can occur.

2021-11-18ata: libahci: Adjust behavior when StorageD3Enable _DSD is setMario Limonciello1-0/+15
The StorageD3Enable _DSD is used for the vendor to indicate that the disk should be opted into or out of a different behavior based upon the platform design. For AMD's Renoir and Green Sardine platforms it's important that any attached SATA storage has transitioned into DevSlp when s2idle is used. If the disk is left in active/partial/slumber, then the system is not able to resume properly. When the StorageD3Enable _DSD is detected, check the system is using s2idle and DevSlp is enabled and if so explicitly wait long enough for the disk to enter DevSlp.
