2023-02-14ice: Change ice_vsi_realloc_stat_arrays() to voidTony Nguyen
smatch reports: smatch warnings: drivers/net/ethernet/intel/ice/ice_lib.c:3612 ice_vsi_rebuild() warn: missing error code 'ret' If an error is encountered for ice_vsi_realloc_stat_arrays(), ret is not assigned an error value so the goto error path would return success. The function, however, only returns 0 so an error will never be reported; due to this, change the function to return void.

2023-02-14wifi: mac80211: fix receiving A-MSDU frames on mesh interfacesFelix Fietkau
The current mac80211 mesh A-MSDU receive path fails to parse A-MSDU packets on mesh interfaces, because it assumes that the Mesh Control field is always directly after the 802.11 header. 802.11-2020 9.3.2.2.2 Figure 9-70 shows that the Mesh Control field is actually part of the A-MSDU subframe header. This makes more sense, since it allows packets for multiple different destinations to be included in the same A-MSDU, as long as RA and TID are still the same. Another issue is the fact that the A-MSDU subframe length field was apparently accidentally defined as little-endian in the standard. In order to fix this, the mesh forwarding path needs happen at a different point in the receive path. ieee80211_data_to_8023_exthdr is changed to ignore the mesh control field and leave it in after the ethernet header. This also affects the source/dest MAC address fields, which now in the case of mesh point to the mesh SA/DA. ieee80211_amsdu_to_8023s is changed to deal with the endian difference and to add the Mesh Control length to the subframe length, since it's not covered by the MSDU length field. With these changes, the mac80211 will get the same packet structure for converted regular data packets and unpacked A-MSDU subframes. The mesh forwarding checks are now only performed after the A-MSDU decap. For locally received packets, the Mesh Control header is stripped away. For forwarded packets, a new 802.11 header gets added.

2023-02-14vfio/ccw: remove WARN_ON during shutdownEric Farman
The logic in vfio_ccw_sch_shutdown() always assumed that the input subchannel would point to a vfio_ccw_private struct, without checking that one exists. The blamed commit put in a check for this scenario, to prevent the possibility of a missing private. The trouble is that check was put alongside a WARN_ON(), presuming that such a scenario would be a cause for concern. But this can be triggered by binding a subchannel to vfio-ccw, and rebooting the system before starting the mdev (via "mdevctl start" or similar) or after stopping it. In those cases, shutdown doesn't need to worry because either the private was never allocated, or it was cleaned up by vfio_ccw_mdev_remove(). Remove the WARN_ON() piece of this check, since there are plausible scenarios where private would be NULL in this path.

2023-02-13net: stmmac: dwc-qos: Make struct dwc_eth_dwmac_data::remove return voidUwe Kleine-König
All implementations of the remove callback return 0 unconditionally. So in dwc_eth_dwmac_remove() there is no error handling necessary. Simplify accordingly. This is a preparation for making struct platform_driver::remove return void, too.

2023-02-13net: stmmac: Make stmmac_dvr_remove() return voidUwe Kleine-König
The function returns zero unconditionally. Change it to return void instead which simplifies some callers as error handing becomes unnecessary. This also makes it more obvious that most platform remove callbacks always return zero.

2023-02-14ata: ahci: Add Tiger Lake UP{3,4} AHCI controllerSimon Gaiser
Mark the Tiger Lake UP{3,4} AHCI controller as "low_power". This enables S0ix to work out of the box. Otherwise this isn't working unless the user manually sets /sys/class/scsi_host/*/link_power_management_policy. Intel lists a total of 4 SATA controller IDs in [1] for those mobile PCHs. This commit just adds the "AHCI" variant since I only tested those.
