platform/x86: x86-android-tablets: fix gpio_secondary_fwnode_init() not working

2026-09-08T19:00:55+00:00

acpi_bus_find_device_by_name() call returns a pointer to the device object on the ACPI bus, aka the ACPI companion device. gpio_secondary_fwnode_init() then continues with setting the secondary fwnode on this device. But this is not the actual physical device for the GPIO controller (e.g. the GPIO controller platform bus device). This mismatch is causing GPIO lookups by secondary fwnode to not work. Modify gpio_secondary_fwnode_init() to instead set the secondary fwnode of the first physical device associated with the ACPI companion device. This fixes the GPIO lookups not working.

treewide: refresh kmalloc_obj() conversions

2026-09-05T04:37:00+00:00

This is another run of the Coccinelle script for converting kmalloc() family of allocations to kmalloc_obj() via the existing rules in scripts/coccinelle/api/kmalloc_objs.cocci This catches both the set of kmalloc() uses added since the first kmalloc_obj() conversions in v7.0 and adds a large group missed in the first pass due to Coccinelle not interacting well with the cleanup.h scoped_...() family of macros[1]. I worked around this with spatch's "--macro-file" argument to a file with all the scoped_...() macros mapped to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control flow indicator I could find. Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc, riscv, and s390 with no new warnings.

platform/x86: x86-android-tablets: use shared battery swnode group on Yoga Tab 2

2026-09-02T11:43:29+00:00

The WM5102 codec software node lenovo_yoga_tab2_830_1050_wm5102 is registered automatically when attached to the codec device via device_add_software_node() in lenovo_yoga_tab2_830_1050_init_codec(). Including it in lenovo_yoga_tab2_830_1050_swnodes is therefore redundant, leaving generic_lipo_hv_4v35_battery_node as the only node needing registration. Switch lenovo_yoga_tab2_830_1050_info and lenovo_yoga_tab2_1380_info to use the shared generic_lipo_hv_4v35_battery_swnodes group directly and drop the custom lenovo_yoga_tab2_830_1050_swnodes array.

platform/x86: x86-android-tablets: drop redundant swnode group on YT3

2026-09-02T11:43:25+00:00

The WM5102 codec software node lenovo_yt3_wm5102 is assigned to the board info swnode pointer in lenovo_yt3_spi_devs. When spi_new_device() instantiates the SPI device, device_add_software_node() automatically registers the software node. Therefore, explicitly registering lenovo_yt3_swnodes via software_node_register_node_group() and listing it in .swnode_group is redundant. Drop the unused node group and registration.

platform/x86: x86-android-tablets: add Crystal Cove GPIO swnode support

2026-09-02T11:43:23+00:00

The crystalcove_gpiochip_node was created when gpiolib supported matching a software node name against the GPIO chip label. Later, gpiolib replaced name matching with firmware node identity mapping, and support for dynamically attaching software nodes to ACPI GPIO chips as secondary firmware nodes was added for Baytrail and Cherryview, but Crystal Cove ("INT33FD:00") was omitted. Consequently, lookups on the unattached Crystal Cove software node fail. Add support for attaching crystalcove_gpiochip_node to the INT33FD:00 ACPI device as a secondary firmware node, and enable it on Lenovo Yoga Tab 2 models.

platform/x86: x86-android-tablets: pass node group to gpio_secondary_fwnode_init()

2026-09-02T11:43:21+00:00

Currently gpio_secondary_fwnode_init() uses a file-scope static gpiochip_node_group variable initialized in probe. Pass the node group directly to gpio_secondary_fwnode_init() as an argument instead of using a global variable. This allows reusing the helper for additional GPIO controllers in subsequent patches.

platform/x86: x86-android-tablets: hold device reference for secondary fwnode teardown

2026-09-02T11:43:20+00:00

In gpio_secondary_fwnode_init(), acpi_bus_find_device_by_name() returns a device reference, but the local dev variable is declared with __free(put_device), dropping the reference at the end of each iteration. Meanwhile, devm_add_action_or_reset() saves the dev pointer for gpio_secondary_unset() without incrementing its reference count, which could lead to a use-after-free during driver teardown if the device is released in the interim. Acquire an explicit device reference with get_device() when registering the devres action, and drop it with put_device() inside gpio_secondary_unset().

platform/x86: x86-android-tablets: fix Arizona GPIO swnode references

2026-09-02T11:43:16+00:00

The standalone arizona_gpiochip_node was created when gpiolib supported matching a software node name against the GPIO chip label ("arizona"). Later, gpiolib replaced name matching with firmware node identity mapping (and eventually dropped the fallback mechanism), causing GPIO lookups on unattached software nodes to fail. In gpio-arizona, the GPIO chip inherits the firmware node of the parent codec device. Fix the lookups by pointing the GPIO property entries directly to the codec device software node (which is attached to the parent device) and dropping the obsolete arizona_gpiochip_node.
