38a285d5d4 pinctrl: realtek: Fix logical error when finding descriptor
The pin descriptor should be returned if the name has been found in the
descriptor table. Remove the negation in the if statement for accurate
retrieval.

0aa5369fdb pinctrl: realtek: Fix some NULL dereference warnings
Just inspecting the code doesn't convince me that this is a real
issue, but the tools complain that it is so I will just handle it.

d48f8a6f4a pinctrl: realtek: Tag unused pins as __maybe_unused
These pin definitions are helpful to have when working with the
driver in the future, so they are in a sense a bit like
documentation. They could be commented out as well, but why.

This should fix these build warnings:

8c58f51ff3 pinctrl: realtek: Fix error handling in probe()
There are several issues in the probe function:
1) of_iomap() return NULL on error but the code checks for error
   pointers.
2) pinctrl_register() is the reverse.  It returns error pointers
   but the code checks for NULL.
3) The error paths need to call iounmap(data->base) before returning
   to avoid a resource leak.

e99ce78030 pinctrl: realtek: Add common pinctrl driver for Realtek DHC RTD SoCs
The RTD SoCs share a similar design for pinmux and pinconfig.
This common pinctrl driver supports different variants within the RTD
SoCs.
