pinctrl: abx500: Fix type of 'argument' variable

2026-06-01T15:35:35+00:00

[ Upstream commit 34006f77890d050e6d80cbee365b5d703c1140b4 ] The argument variable is assigned the return value of pinconf_to_config_argument(), which returns a u32. Change its type from enum pin_config_param to unsigned int to correctly store the configuration argument.

pinctrl: intel: Fix the revision for new features (1kOhm PD, HW debouncer)

[ Upstream commit a4337a24d13e9e3b98a113e71d6b80dc5ed5f8c4 ] The 1kOhm pull down and hardware debouncer are features of the revision 0.92 of the Chassis specification. Fix that in the code accordingly. Signed-off-by: Andy Shevchenko Signed-off-by: Sasha Levin

pinctrl: mediatek: common: Fix probe failure for devices without EINT

2026-04-18T08:33:24+00:00

[ Upstream commit 8f9f64c8f90dca07d3b9f1d7ce5d34ccd246c9dd ] Some pinctrl devices like mt6397 or mt6392 don't support EINT at all, but the mtk_eint_init function is always called and returns -ENODEV, which then bubbles up and causes probe failure. To address this only call mtk_eint_init if EINT pins are present. Tested on Xiaomi Mi Smart Clock x04g (mt6392).

pinctrl: single: fix refcount leak in pcs_add_gpio_func()

2026-03-04T12:19:49+00:00

[ Upstream commit 353353309b0f7afa407df29e455f9d15b5acc296 ] of_parse_phandle_with_args() returns a device_node pointer with refcount incremented in gpiospec.np. The loop iterates through all phandles but never releases the reference, causing a refcount leak on each iteration. Add of_node_put() calls to release the reference after extracting the needed arguments and on the error path when devm_kzalloc() fails. This bug was detected by our static analysis tool and verified by my code review.

pinctrl: equilibrium: Fix device node reference leak in pinbank_init()

2026-03-04T12:19:47+00:00

[ Upstream commit c0b4a4feeb43305a754893d8d9c6b2b5a52d45ac ] When calling of_parse_phandle_with_fixed_args(), the caller is responsible to call of_node_put() to release the reference of device node. In pinbank_init(), the reference of the node obtained from the "gpio-ranges" property is never released, resulting in a reference count leak. Add the missing of_node_put() call to fix the leak.
