After the commit acf137951367 ("pinctrl: core: Return selector to the
pinctrl driver") and the commit 47f1242d19c3 ("pinctrl: pinmux: Return
selector to the pinctrl driver"), it's necessary to add the fixes
needed for the pin controller drivers to use the appropriate returned
selector for a negative error number returned in case of the fail at
these functions. Otherwise, the driver would have a failed probe and
that causes boot message cannot correctly output and devices fail
to acquire their own pins.

Applied on top of Tony's patches on the fixes branch.

Now there are fixes piling on top of fixes and I am starting to feel
insecure of pushing this to v4.18 and I feel like letting these
fixes go to v4.19 (it can be picked to stable from there).

Tony: do you think there could be more fallout like this?
