…nel/git/linusw/linux-pinctrl

Pull pin control fixes from Linus Walleij:

 - Tag Intel pin control as supported in MAINTAINERS

 - Fix a NULL pointer exception in the Aspeed driver

 - Correct some NAND functions in the Sunxi A83T driver

 - Use the right offset for some Sunxi pins

 - Fix a zero base offset in the Freescale (NXP) i.MX93

 - Fix the IRQ support in the STM32 driver
