net: ethernet: ti: netcp: Standardize knav_dma_open_channel to return NULL on error

2025-11-05T03:15:36Z

Make knav_dma_open_channel consistently return NULL on error instead of ERR_PTR. Currently the header include/linux/soc/ti/knav_dma.h returns NULL when the driver is disabled, but the driver implementation does not even return NULL or ERR_PTR on failure, causing inconsistency in the users. This results in a crash in netcp_free_navigator_resources as followed (trimmed): Unhandled fault: alignment exception (0x221) at 0xfffffff2 [fffffff2] *pgd=80000800207003, *pmd=82ffda003, *pte=00000000 Internal error: : 221 [#1] SMP ARM Modules linked in: CPU: 0 UID: 0 PID: 1 Comm: swapper/0 Not tainted 6.17.0-rc7 #1 NONE Hardware name: Keystone PC is at knav_dma_close_channel+0x30/0x19c LR is at netcp_free_navigator_resources+0x2c/0x28c [...

TRIM...] Standardize the error handling by making the function return NULL on all error conditions. The API is used in just the netcp_core.c so the impact is limited. Note, this change, in effect reverts commit 5b6cb43b4d62 ("net: ethernet: ti: netcp_core: return error while dma channel open issue"), but provides a less error prone implementation.

Pull pin control updates from Linus Walleij: "We have GPIO awareness in the pin control core and an interesting AAEON driver. Core changes: - Allow pins to be identified/marked as GPIO mode with a special callback. The pin controller core is now "aware" if a pin is in GPIO mode if the callback is implemented in the driver, and can thus be marked as "strict", i.e. disallowing simultaneous use of a line as GPIO and another function such as I2C. This is enabled in the Qualcomm TLMM driver and also implemeted from day 1 in the new Broadcom STB driver - Rename the pin config option PIN_CONFIG_OUTPUT to PIN_CONFIG_LEVEL to better describe what the config is doing, as well as making it more intuitive what shall be returned when reading this property New drivers: - Qualcomm SDM660 LPASS LPI TLMM pin controller subdriver - Qualcomm Glymur family pin controller driver - Broadcom STB family pin controller driver - Tegra186 pin controller driver - AAEON UP pin controller support. This is some special pin controller that works as an external advanced line MUX and amplifier for signals from an Intel SoC. A cooperative effort with the GPIO maintainer was needed to reach a solution where we reuse code from the GPIO aggregator/forwarder driver - Renesas RZ/T2H and RZ/N2H pin controller support - Axis ARTPEC-8 subdriver for the Samsung pin controller driver Improvements: - Output enable (OEN) support in the Renesas RZG2L driver - Properly support bias pull up/down in the pinctrl-single driver - Move over all GPIO portions using generic MMIO GPIO to the new generic GPIO chip management which has a nice and separate API - Proper DT bindings for some older Broadcom SoCs - External GPIO (EGPIO) support in the Qualcomm SM8250 Deleted code: - Dropped the now unused Samsung S3C24xx drivers" * tag 'pinctrl-v6.18-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (75 commits) pinctrl: use more common syntax for compound literals pinctrl: Simplify printks with pOF format pinctrl: qcom: Add SDM660 LPASS LPI TLMM dt-bindings: pinctrl: qcom: Add SDM660 LPI pinctrl pinctrl: qcom: lpass-lpi: Add ability to use custom pin offsets pinctrl: qcom: Add glymur pinctrl driver dt-bindings: pinctrl: qcom: Add Glymur pinctrl pinctrl: qcom: sm8250: Add egpio support pinctrl: generic: rename PIN_CONFIG_OUTPUT to LEVEL pinctrl: keembay: fix double free in keembay_build_functions() pinctrl: spacemit: fix typo in PRI_TDI pin name pinctrl: eswin: Fix regulator error check and Kconfig dependency pinctrl: bcm: Add STB family pin controller driver dt-bindings: pinctrl: Add support for Broadcom STB pin controller pinctrl: qcom: make the pinmuxing strict pinctrl: qcom: mark the `gpio` and `egpio` pins function as non-strict functions pinctrl: qcom: add infrastructure for marking pin functions as GPIOs pinctrl: allow to mark pin functions as requestable GPIOs pinctrl: qcom: use generic pin function helpers pinctrl: make struct pinfunction a pointer in struct function_desc ...

Apple SoC driver updates for 6.18 Krzysztof Kozlowski asked us to move away from generic compatibles: - Adjust all dt-bindings to use apple,t8103-XXXX instead of apple,XXXX as fallback and add a comment that the old generic list should no longer be extended. - Add new fallback compatibles to pinctrl, pmdomain, spi, and mca drivers. These changes have been Acked by their subsystem maintainers to be merged through our tree together with the dt-bindings. Support for pre-M1 Apple Silicon: - SART and mailbox gain support for Apple's A11, which are both required for NVMe. - NVMe also gains support for Apple's A11 and the nvme maintainers prefer that we merge this through the soc tree together with the mailbox and SART changes. - SPMI compatibles for A11 and T2 have been added, also going through the soc tree due to conflicts with the generic compatible removal and because no driver change is required.
