2023-08-09mmc: sunplus: Fix error handling in spmmc_drv_probe()Harshit Mogalapalli
When mmc allocation succeeds, the error paths are not freeing mmc. Fix the above issue by changing mmc_alloc_host() to devm_mmc_alloc_host() to simplify the error handling. Remove label 'probe_free_host' as devm_* api takes care of freeing, also remove mmc_free_host() from remove function as devm_* takes care of freeing.

2023-08-09mmc: sunplus: fix return value check of mmc_add_host()Wei Chen
mmc_add_host() may return error, if we ignore its return value, 1. the memory allocated in mmc_alloc_host() will be leaked 2. null-ptr-deref will happen when calling mmc_remove_host() in remove function spmmc_drv_remove() because deleting not added device. Fix this by checking the return value of mmc_add_host(). Moreover, I fixed the error handling path of spmmc_drv_probe() to clean up.

2023-08-09ACPI: thermal: Do not attach private data to ACPI handlesRafael J. Wysocki
The ACPI thermal driver uses acpi_bus_attach_private_data() to attach the thermal zone object to the ACPI handle of the thermal zone and acpi_bus_detach_private_data() to clean that up, but it never uses acpi_bus_get_private_data() to retrieve that object.

The workaround implemented in commit 3222b5b613db ("net: enetc: initialize RFS/RSS memories for unused ports too") is no longer effective after commit 6fffbc7ae137 ("PCI: Honor firmware's device disabled status"). Thus, it has introduced a regression and we see AER errors being reported again: $ ip link set sw2p0 up && dhclient -i sw2p0 && ip addr show sw2p0 fsl_enetc 0000:00:00.2 eno2: configuring for fixed/internal link mode fsl_enetc 0000:00:00.2 eno2: Link is Up - 2.5Gbps/Full - flow control rx/tx mscc_felix 0000:00:00.5 swp2: configuring for fixed/sgmii link mode mscc_felix 0000:00:00.5 swp2: Link is Up - 1Gbps/Full - flow control off sja1105 spi2.2 sw2p0: configuring for phy/rgmii-id link mode sja1105 spi2.2 sw2p0: Link is Up - 1Gbps/Full - flow control off pcieport 0000:00:1f.0: AER: Multiple Corrected error received: 0000:00:00.0 pcieport 0000:00:1f.0: AER: can't find device of ID0000 Rob's suggestion is to reimplement the enetc driver workaround as a PCI fixup, and to modify the PCI core to run the fixups for all PCI functions. This change handles the first part. We refactor the common code in enetc_psi_create() and enetc_psi_destroy(), and use the PCI fixup only for those functions for which enetc_pf_probe() won't get called. This avoids some work being done twice for the PFs which are enabled.

2023-08-09PCI: move OF status = "disabled" detection to dev->match_driverVladimir Oltean
The blamed commit has broken probing on arch/arm64/boot/dts/freescale/fsl-ls1028a.dtsi when &enetc_port0 (PCI function 0) has status = "disabled". Background: pci_scan_slot() has logic to say that if the function 0 of a device is absent, the entire device is absent and we can skip the other functions entirely. Traditionally, this has meant that pci_bus_read_dev_vendor_id() returns an error code for that function. However, since the blamed commit, there is an extra confounding condition: function 0 of the device exists and has a valid vendor id, but it is disabled in the device tree. In that case, pci_scan_slot() would incorrectly skip the entire device instead of just that function. In the case of NXP LS1028A, status = "disabled" does not mean that the PCI function's config space is not available for reading. It is, but the Ethernet port is just not functionally useful with a particular SerDes protocol configuration (0x9999) due to pinmuxing constraints of the Soc. So, pci_scan_slot() skips all other functions on the ENETC ECAM (enetc_port1, enetc_port2, enetc_mdio_pf3 etc) when just enetc_port0 had to not be probed. There is an additional regression introduced by the change, caused by its fundamental premise. The enetc driver needs to run code for all PCI functions, regardless of whether they're enabled or not in the device tree. That is no longer possible if the driver's probe function is no longer called. But Rob recommends that we move the of_device_is_available() detection to dev->match_driver, and this makes the PCI fixups still run on all functions, while just probing drivers for those functions that are enabled. So, a separate change in the enetc driver will have to move the workarounds to a PCI fixup.

2023-08-08PCI: acpiphp: Use pci_assign_unassigned_bridge_resources() only for non-root busIgor Mammedov
40613da52b13 ("PCI: acpiphp: Reassign resources on bridge if necessary") changed acpiphp hotplug to use pci_assign_unassigned_bridge_resources() which depends on bridge being available, however enable_slot() can be called without bridge associated: 1. Legitimate case of hotplug on root bus (widely used in virt world) 2. A (misbehaving) firmware, that sends ACPI Bus Check notifications to non existing root ports (Dell Inspiron 7352/0W6WV0), which end up at enable_slot(..., bridge = 0) where bus has no bridge assigned to it. acpihp doesn't know that it's a bridge, and bus specific 'PCI subsystem' can't augment ACPI context with bridge information since the PCI device to get this data from is/was not available. Issue is easy to reproduce with QEMU's 'pc' machine, which supports PCI hotplug on hostbridge slots. To reproduce, boot kernel at commit 40613da52b13 in VM started with following CLI (assuming guest root fs is installed on sda1 partition): # qemu-system-x86_64 -M pc -m 1G -enable-kvm -cpu host \ -monitor stdio -serial file:serial.log \ -kernel arch/x86/boot/bzImage \ -append "root=/dev/sda1 console=ttyS0" \ guest_disk.img Once guest OS is fully booted at qemu prompt: (qemu) device_add e1000 (check serial.log) it will cause NULL pointer dereference at: void pci_assign_unassigned_bridge_resources(struct pci_dev *bridge) { struct pci_bus *parent = bridge->subordinate; BUG: kernel NULL pointer dereference, address: 0000000000000018 ? pci_assign_unassigned_bridge_resources+0x1f/0x260 enable_slot+0x21f/0x3e0 acpiphp_hotplug_notify+0x13d/0x260 acpi_device_hotplug+0xbc/0x540 acpi_hotplug_work_fn+0x15/0x20 process_one_work+0x1f7/0x370 worker_thread+0x45/0x3b0 The issue was discovered on Dell Inspiron 7352/0W6WV0 laptop with following sequence: 1. Suspend to RAM 2. Wake up with the same backtrace being observed: 3. 2nd suspend to RAM attempt makes laptop freeze Fix it by using __pci_bus_assign_resources() instead of pci_assign_unassigned_bridge_resources() as we used to do, but only in case when bus doesn't have a bridge associated (to cover for the case of ACPI event on hostbridge or non existing root port). That lets us keep hotplug on root bus working like it used to and at the same time keeps resource reassignment usable on root ports (and other 1st level bridges) that was fixed by 40613da52b13.
