Merge tag 'pinctrl-v6.9-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control fixes from Linus Walleij: - Fix a double-free in the pinctrl_enable() errorpath - Fix a refcount leak in pinctrl_dt_to_map() - Fix selecting the GPIO pin control state and the UART3 pin config group in the Intel Baytrail driver - Fix readback of schmitt trigger status in the Mediatek Paris driver, along with some semantic pin config issues in this driver - Fix a pin suffix typo in the Meson A1 driver - Fix an erroneous register offset in he Aspeed G6 driver - Fix an inconsistent lock state and the interrupt type on resume in the Renesas RZG2L driver - Fix some minor confusion in the Renesas DT bindings * tag 'pinctrl-v6.9-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: pinctrl: renesas: rzg2l: Configure the interrupt type on resume pinctrl: devicetree: fix refcount leak in pinctrl_dt_to_map() pinctrl: baytrail: Add pinconf group for uart3 pinctrl: baytrail: Fix selecting gpio pinctrl state pinctrl: mediatek: paris: Rework support for PIN_CONFIG_{INPUT,OUTPUT}_ENABLE pinctrl: mediatek: paris: Fix PIN_CONFIG_INPUT_SCHMITT_ENABLE readback pinctrl: core: delete incorrect free in pinctrl_enable() pinctrl/meson: fix typo in PDM's pin name pinctrl: pinctrl-aspeed-g6: Fix register offset for pinconf of GPIOR-T pinctrl: renesas: rzg2l: Execute atomically the interrupt configuration dt-bindings: pinctrl: renesas,rzg2l-pinctrl: Allow 'input' and 'output-enable' properties
