pinctrl: Export pinctrl_get_group_selector()

2026-06-15T13:01:15+00:00

The recently added UltraRISC DP1000 is using this symbol, and in a reasonable way as well, so export it.

pinctrl: core: Make pin group callbacks optional for pin-only drivers

2026-05-25T07:51:22+00:00

Currently, the pinctrl core strictly requires all drivers to implement .get_groups_count and .get_group_name callbacks in their pinctrl_ops. However, for simple pinctrl drivers that act purely as GPIO controllers and pin-specific configuration proxies, without any concept of muxing or pin groups, this strict requirement forces the implementation of dummy callbacks just to satisfy pinctrl_check_ops(). Relax this requirement for pin-only drivers by making the group callbacks optional when no muxing or group pin configuration support is provided. Update the core and debugfs helpers to check for the existence of these callbacks before invoking them. Drivers that provide muxing or group pin configuration operations still must implement group enumeration and naming callbacks, and are rejected at registration time if they do not.

pinctrl: introduce pinctrl_gpio_get_config()

2026-03-24T12:50:30+00:00

This is a counterpart of pinctrl_gpio_set_config(), which will be used to implement the ->get() interface in a GPIO driver for SCMI. This also requires that we create a stub so pin_config_get_for_pin() can build when CONFIG_PINCONF is disabled.

pinctrl: Prefer IS_ERR_OR_NULL over manual NULL check

pinctrl: core: use dev_err_probe() when applying state

2026-03-03T07:30:33+00:00

When applying a pinctrl state, -EPROBE_DEFER may be returned if dependencies are not ready and the consumer will retry probing. This is normal probe ordering behaviour and not a real error. However, pinctrl core currently logs: "Error applying setting, reverse things back" even when the return value is -EPROBE_DEFER, resulting in noisy boot-time error messages. Replace dev_err() with dev_err_probe() to handle -EPROBE_DEFER consistently and suppress error logging for deferred probes. No functional change intended.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook
