Subject: [PATCH 0/3] pinctrl: mcp23s08: Fixups for mcp23x17

Hi,
I'm in the process of adding a device tree overlay for the PiFace
Digital Raspberry Pi daughter board [0]. It's an mcp23s17 SPI GPIO port
expander. In doing so, I noticed some errors with the mcp23s08 driver.

This series adds my fixups to (which builds successfully):

	v5.8-13252-gcf4a66ae5e4a

But I have only tested them on (rpi-5.4.y):

	v5.4.51-1078-g92834e4bb4ce

They're quite trivial and backwards compatible, although I might be
wrong about "interrupt-controller". Can someone please confirm?

Many thanks,
Thomas
