[PATCH v2 0/4] mcp23s08 fixes

[Jan Kundrát <jan.kundrat@xxxxxxxxx>]

My HW has two physical chips on the same SPI CS, and that's a bit
problematic. I've already solved conflicts in, e.g., debugfs entries for
pinctrl and made it possible to distinguish the chip labels, but there
was no way of attaching names to the individual GPIO lines from the DT.
One approach suggested by Phil back in last February [1] was to
introduce intermediate nodes to the DT.

Changes from v1:

- dev_dbg for writes of sunsupported pinctrl values
- exporting symbol devprop_gpiochip_set_names
- removal of superfluous mcp23s08's dbg_show

Jan Kundrát (4):
  pinctrl: mcp23s08: Do not complain about unsupported params
  gpiolib: export devprop_gpiochip_set_names()
  pinctrl: mcp23s08: work around GPIO line naming
  pinctrl: mcp23s08: debugfs: remove custom printer
