pinctrl: core: Don't use "proxy" headers

2026-03-27T09:00:33+00:00

Update header inclusions to follow IWYU (Include What You Use) principle. Signed-off-by: Andy Shevchenko Signed-off-by: Linus Walleij

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

Prefer using IS_ERR_OR_NULL() over using IS_ERR() and a manual NULL check. Change generated with coccinelle. To: Linus Walleij Cc: linux-gpio@vger.kernel.org Cc: linux-kernel@vger.kernel.org Signed-off-by: Philipp Hahn Signed-off-by: Linus Walleij

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

pinctrl: core: Remove duplicate error messages

2026-02-03T00:18:18+00:00

pinctrl_claim_hogs() is covered to report any error via message. Since that it's not needed in the callers. Signed-off-by: Andy Shevchenko Reviewed-by: Bartosz Golaszewski Signed-off-by: Linus Walleij

pinctrl: core: Simplify devm_pinctrl_*()

2026-02-03T00:18:18+00:00

Use devm_add_action_or_reset() instead of devres_alloc() and devres_add(), which works the same. This will simplify the code. There is no functional changes. Signed-off-by: Andy Shevchenko Reviewed-by: Bartosz Golaszewski Signed-off-by: Linus Walleij
