2025-05-20bnxt_en: Fix netdev locking in ULP IRQ functionsMichael Chan
netdev_lock is already held when calling bnxt_ulp_irq_stop() and bnxt_ulp_irq_restart(). When converting rtnl_lock to netdev_lock, the original code was rtnl_dereference() to indicate that rtnl_lock was already held. rcu_dereference_protected() is the correct conversion after replacing rtnl_lock with netdev_lock. Add a new helper netdev_lock_dereference() similar to rtnl_dereference().

2025-05-20net: dwmac-sun8i: Use parsed internal PHY address instead of 1Paul Kocialkowski
While the MDIO address of the internal PHY on Allwinner sun8i chips is generally 1, of_mdio_parse_addr is used to cleanly parse the address from the device-tree instead of hardcoding it. A commit reworking the code ditched the parsed value and hardcoded the value 1 instead, which didn't really break anything but is more fragile and not future-proof. Restore the initial behavior using the parsed address returned from the helper.

2025-05-20wifi: ath12k: fix mac pdev frequency range updateAditya Kumar Singh
The current implementation of per-pdev frequency range updates assumes that each pdev supports only a single band. As a result in ath12k_regd_update(), bands are handled using an if-else structure, which limits updates to only one of the band per pdev. This assumption does not hold for all chipsets. For example, the WCN7850 supports multiple bands within a single pdev. Hence to accommodate such cases, update the logic to account for all band cases by handling each band in a separate if conditions instead of the previous if-else structure.

2025-05-20gpiolib: don't crash on enabling GPIO HOG pinsDmitry Baryshkov
On Qualcomm platforms if the board uses GPIO hogs msm_pinmux_request() calls gpiochip_line_is_valid(). After commit 8015443e24e7 ("gpio: Hide valid_mask from direct assignments") gpiochip_line_is_valid() uses gc->gpiodev, which is NULL when GPIO hog pins are being processed. Thus after this commit using GPIO hogs causes the following crash. In order to fix this, verify that gc->gpiodev is not NULL. Note: it is not possible to reorder calls (e.g. by calling msm_gpio_init() before pinctrl registration or by splitting pinctrl_register() into _and_init() and pinctrl_enable() and calling the latter function after msm_gpio_init()) because GPIO chip registration would fail with EPROBE_DEFER if pinctrl is not enabled at the time of registration. pc : gpiochip_line_is_valid+0x4/0x28 lr : msm_pinmux_request+0x24/0x40 sp : ffff8000808eb870 x29: ffff8000808eb870 x28: 0000000000000000 x27: 0000000000000000 x26: 0000000000000000 x25: ffff726240f9d040 x24: 0000000000000000 x23: ffff7262438c0510 x22: 0000000000000080 x21: ffff726243ea7000 x20: ffffab13f2c4e698 x19: 0000000000000080 x18: 00000000ffffffff x17: ffff726242ba6000 x16: 0000000000000100 x15: 0000000000000028 x14: 0000000000000000 x13: 0000000000002948 x12: 0000000000000003 x11: 0000000000000078 x10: 0000000000002948 x9 : ffffab13f50eb5e8 x8 : 0000000003ecb21b x7 : 000000000000002d x6 : 0000000000000b68 x5 : 0000007fffffffff x4 : ffffab13f52f84a8 x3 : ffff8000808eb804 x2 : ffffab13f1de8190 x1 : 0000000000000080 x0 : 0000000000000000 Call trace: gpiochip_line_is_valid+0x4/0x28 (P) pin_request+0x208/0x2c0 pinmux_enable_setting+0xa0/0x2e0 pinctrl_commit_state+0x150/0x26c pinctrl_enable+0x6c/0x2a4 pinctrl_register+0x3c/0xb0 devm_pinctrl_register+0x58/0xa0 msm_pinctrl_probe+0x2a8/0x584 sdm845_pinctrl_probe+0x20/0x88 platform_probe+0x68/0xc0 really_probe+0xbc/0x298 __driver_probe_device+0x78/0x12c driver_probe_device+0x3c/0x160 __device_attach_driver+0xb8/0x138 bus_for_each_drv+0x84/0xe0 __device_attach+0x9c/0x188 device_initial_probe+0x14/0x20 bus_probe_device+0xac/0xb0 deferred_probe_work_func+0x8c/0xc8 process_one_work+0x208/0x5e8 worker_thread+0x1b4/0x35c kthread+0x144/0x220 ret_from_fork+0x10/0x20 Code: b5fffba0 17fffff2 9432ec27 f9400400 (f9428800) Fixes: 8015443e24e7 ("gpio: Hide valid_mask from direct assignments") Reported-by: Doug Anderson <dianders@chromium.org> Closes: https://lore.kernel.org/r/CAD=FV=Vg8_ZOLgLoC4WhFPzhVsxXFC19NrF38W6cW_W_3nFjbw@mail.gmail.com Tested-by: Douglas Anderson <dianders@chromium.org> Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com> Reviewed-by: Matti Vaittinen <mazziesaccount@gmail.com> Acked-by: Bartosz Golaszewski <bartosz.golaszewski@linaro.org> Link: https://lore.kernel.org/20250513-pinctrl-msm-fix-v2-1-249999af0fc1@oss.qualcomm.com Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

io_uring_cmd_import_fixed_vec() is declared in both include/linux/io_uring/cmd.h and io_uring/uring_cmd.h. The declarations are identical (if redundant) for CONFIG_IO_URING=y. But if CONFIG_IO_URING=N, include/linux/io_uring/cmd.h declares the function as static inline while io_uring/uring_cmd.h declares it as extern. This causes linker errors if the declaration in io_uring/uring_cmd.h is used. Remove the declaration in io_uring/uring_cmd.h to avoid linker errors and prevent the declarations getting out of sync.

Axel Forsman <axfo@kvaser.com> says: This patch series fixes a couple of race conditions in the kvaser_pciefd driver surfaced by enabling MSI interrupts and the new Kvaser PCIe 8xCAN. Changes since version 2: * Rebase onto linux-can/main to resolve del_timer()/timer_delete() merge conflict. * Reword 2nd commit message slightly. Changes since version 1: * Change type of srb_cmd_reg from "__le32 __iomem *" to "void __iomem *". * Maintain TX FIFO count in driver instead of querying HW. * Stop queue at end of .start_xmit() if full.

2025-05-20can: kvaser_pciefd: Continue parsing DMA buf after dropped RXAxel Forsman
Going bus-off on a channel doing RX could result in dropped packets. As netif_running() gets cleared before the channel abort procedure, the handling of any last RDATA packets would see netif_rx() return non-zero to signal a dropped packet. kvaser_pciefd_read_buffer() dealt with this "error" by breaking out of processing the remaining DMA RX buffer. Only return an error from kvaser_pciefd_read_buffer() due to packet corruption, otherwise handle it internally.

2025-05-20can: kvaser_pciefd: Fix echo_skb raceAxel Forsman
The functions kvaser_pciefd_start_xmit() and kvaser_pciefd_handle_ack_packet() raced to stop/wake TX queues and get/put echo skbs, as kvaser_pciefd_can->echo_lock was only ever taken when transmitting and KCAN_TX_NR_PACKETS_CURRENT gets decremented prior to handling of ACKs. E.g., this caused the following error: can_put_echo_skb: BUG! echo_skb 5 is occupied! Instead, use the synchronization helpers in netdev_queues.h. As those piggyback on BQL barriers, start updating in-flight packets and bytes counts as well.

We added the documentation in ext4_map_blocks() for usage of EXT4_GET_BLOCKS_QUERY_LAST_IN_LEAF flag. But It's better to add a WARN_ON_ONCE in case if anyone tries using this flag with CREATE to avoid a random issue later.
