[PATCH v2 0/4] arm64: dts: marvell: cn913x-solidrun: fix sata ports status

by Josua Mayer

The SolidRun CN9130 SoC based boards have a variety of functional problems, in particular - SATA ports - CN9132 CEX-7 eMMC - CN9132 Clearfog PCI-E x2 / x4 ports are not functional. The SATA issue was recently introduced via changes to the armada-cp11x.dtsi, wheras the eMMC and SPI problems were present in the board dts from the very beginning. This patch-set aims to resolve the problems after testing on Debian 13 release (Linux v6.12). Signed-off-by: Josua Mayer <josua(a)solid-run.com> --- Changes in v2: - fixed mistakes in the original board device-trees that caused functional issues with eMMC and pci. - Link to v1: https://lore.kernel.org/r/20250911-cn913x-sr-fix-sata-v1-1-9e72238d0988@sol… --- Josua Mayer (4): arm64: dts: marvell: cn913x-solidrun: fix sata ports status arm64: dts: marvell: cn9132-clearfog: disable eMMC high-speed modes arm64: dts: marvell: cn9132-clearfog: fix multi-lane pci x2 and x4 ports arm64: dts: marvell: cn9130-sr-som: add missing properties to emmc arch/arm64/boot/dts/marvell/cn9130-cf.dtsi | 7 ++++--- arch/arm64/boot/dts/marvell/cn9130-sr-som.dtsi | 2 ++ arch/arm64/boot/dts/marvell/cn9131-cf-solidwan.dts | 6 ++++-- arch/arm64/boot/dts/marvell/cn9132-clearfog.dts | 22 ++++++++++++++++------ arch/arm64/boot/dts/marvell/cn9132-sr-cex7.dtsi | 8 ++++++++ 5 files changed, 34 insertions(+), 11 deletions(-) --- base-commit: 8f5ae30d69d7543eee0d70083daf4de8fe15d585 change-id: 20250911-cn913x-sr-fix-sata-5c737ebdb97f Best regards, -- Josua Mayer <josua(a)solid-run.com>

[PATCH] nvdimm: ndtest: Add check for devm_kcalloc() allocations in ndtest_probe()

by Guangshuo Li

devm_kcalloc() may fail. ndtest_probe() allocates three DMA address arrays (dcr_dma, label_dma, dimm_dma) and later unconditionally uses them in ndtest_nvdimm_init(), which can lead to a NULL pointer dereference on allocation failure. Add NULL checks for all three allocations and return -ENOMEM if any allocation fails.

[PATCH] usb: xhci: Check kcalloc_node() when allocating interrupter array in xhci_mem_init()

by Guangshuo Li

kcalloc_node() may fail. When the interrupter array allocation returns NULL, subsequent code uses xhci->interrupters (e.g. in xhci_add_interrupter() and in cleanup paths), leading to a potential NULL pointer dereference. Check the allocation and bail out to the existing fail path to avoid the NULL dereference.

[PATCH] net: liquidio: fix overflow in octeon_init_instr_queue()

by Alexey Nepomnyashih

The expression `(conf->instr_type == 64) << iq_no` can overflow because `iq_no` may be as high as 64 (`CN23XX_MAX_RINGS_PER_PF`). Casting the operand to `u64` ensures correct 64-bit arithmetic.

[PATCH wireless] wifi: mac80211: do not permit 40 MHz EHT operation on 5/6 GHz

by Miri Korenblit

From: Benjamin Berg <benjamin.berg(a)intel.com> The EHT PHY requirements state that 80 MHz must be supported on the 5 and 6 GHz bands unless the STA is 20 MHz only. So if the channel width is limited to 40 MHz on a band other than 2.4 GHz, then disable EHT and downgrade to HE. The primary case where this can happen is if the hardware disables puncturing using IEEE80211_HW_DISALLOW_PUNCTURING.
