Merge tag 'pinctrl-v5.18-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control fixes from Linus Walleij:

 - Fix some register offsets on Intel Alderlake

 - Fix the order the UFS and SDC pins on Qualcomm SM6350

 - Fix a build error in Mediatek Moore.

 - Fix a pin function table in the Sunplus SP7021.

 - Fix some Kconfig and static keywords on the Samsung Tesla FSD SoC.

 - Fix up the EOI function for edge triggered IRQs and keep the block
   clock enabled for level IRQs in the STM32 driver.

 - Fix some bits and order in the Rockchip RK3308 driver.

 - Handle the errorpath in the Pistachio driver probe() properly.
