[PATCH v2 2/4] ASoC: cs4271: Disable regulators in component_probe() error path

by Herve Codina

The commit 9a397f473657 ("ASoC: cs4271: add regulator consumer support") has introduced regulators in the driver. Regulators are enabled at the beginning of component_probe() but they are not disabled on errors. This can lead to unbalanced enable/disable. Fix the error path to disable regulators on errors.

[PATCH] most: usb: fix double free on late probe failure

by Johan Hovold

The MOST subsystem has a non-standard registration function which frees the interface on registration failures and on deregistration. This unsurprisingly leads to bugs in the MOST drivers, and a couple of recent changes turned a reference underflow and use-after-free in the USB driver into several double free and a use-after-free on late probe failures.

[PATCH v5 1/2] dma-mapping: benchmark: Restore padding to ensure uABI remained consistent

by Qinxin Xia

The padding field in the structure was previously reserved to maintain a stable interface for potential new fields, ensuring compatibility with user-space shared data structures. However,it was accidentally removed by tiantao in a prior commit, which may lead to incompatibility between user space and the kernel. This patch reinstates the padding to restore the original structure layout and preserve compatibility.

[PATCH v2 1/2] PCI: Allow per function PCI slots

by Farhan Ali

On s390 systems, which use a machine level hypervisor, PCI devices are always accessed through a form of PCI pass-through which fundamentally operates on a per PCI function granularity. This is also reflected in the s390 PCI hotplug driver which creates hotplug slots for individual PCI functions. Its reset_slot() function, which is a wrapper for zpci_hot_reset_device(), thus also resets individual functions. Currently, the kernel's PCI_SLOT() macro assigns the same pci_slot object to multifunction devices. This approach worked fine on s390 systems that only exposed virtual functions as individual PCI domains to the operating system. Since commit 44510d6fa0c0 ("s390/pci: Handling multifunctions") s390 supports exposing the topology of multifunction PCI devices by grouping them in a shared PCI domain. When attempting to reset a function through the hotplug driver, the shared slot assignment causes the wrong function to be reset instead of the intended one. It also leaks memory as we do create a pci_slot object for the function, but don't correctly free it in pci_slot_release(). Add a flag for struct pci_slot to allow per function PCI slots for functions managed through a hypervisor, which exposes individual PCI functions while retaining the topology.

[PATCH net] virtio-net: calculate header alignment mask based on features

by Jason Wang

Commit 56a06bd40fab ("virtio_net: enable gso over UDP tunnel support.") switches to check the alignment of the virtio_net_hdr_v1_hash_tunnel even when doing the transmission even if the feature is not negotiated. This will cause a series performance degradation of pktgen as the skb->data can't satisfy the alignment requirement due to the increase of the header size then virtio-net must prepare at least 2 sgs with indirect descriptors which will introduce overheads in the device. Fixing this by calculate the header alignment during probe so when tunnel gso is not negotiated, we can less strict. Pktgen in guest + XDP_DROP on TAP + vhost_net shows the TX PPS is recovered from 2.4Mpps to 4.45Mpps. Note that we still need a way to recover the performance when tunnel gso is enabled, probably a new vnet header format. Fixes: 56a06bd40fab ("virtio_net: enable gso over UDP tunnel support.")

[PATCH] drm/bridge: sii902x: Fix device node reference leak sii902x_probe

of_graph_get_endpoint_by_regs() gets a reference to the endpoint node to read the "bus-width" property but fails to call of_node_put() to release the reference, causing a reference count leak.
