[PATCHv2 0/5] pinctrl fixes for generic functions and groups

[Tony Lindgren <tony@atomide.com>]

Here are fixes to the race issues for generic group and functions
reported by H. Nikolaus Schaller <hns@goldelico.com>. I have not seen
the issue here myself, so please test to see if this is sufficient.

I've also fixed rza1 in addition to pinctrl-single. Please also check
the drivers pinctrl-mt7622.c and pinctrl-ingenic.c if mutex fixes are
needed there.

Regards,

Tony

Changes since v1:

- Check if a function or group already exists as suggested by
  Andy Shevchenko

- Make sure we always have a valid name for functions and groups
  as suggested by Christ van Willegen

- Prettify rza1 variables as suggested by Jacopo Mondi
