pinctrl_register_mappings is called in the pdata case, however a call to
pinctrl_unregister_mappings is missing causing the mappings to be leaked
on driver unbind. Add the missing call to correct this issue.

GPL-2.0-only is the preferred way of expressing v2 of the GPL, so switch
to that. Remove some redundant copyright notices and correct some
instances where the wrong comment type has been used in header files.

The change adds explicit inclusion of linux/pinctrl/machine.h header
to the only needed pinctrl-madera-core.c file, and therefore inclusion
of pinctrl/machine.h header from pinctrl/pinconf.h can be removed.
The change is preparatory to a follow-up reversal of commit f07512e615
("pinctrl/pinconfig: add debug interface").

There is a potential execution path in which variable *ret* is checked
in an IF statement, and then its value is used to report an error at
line 659 without being properly initialized previously:
659 if (ret)
660 dev_err(priv->dev, "Failed to write to 0x%x (%d)\n", reg, ret);
Fix this by initializing variable *ret* to 0 in order to
avoid unpredictable or unintended results.

Merge tag 'v4.19-rc6' into devel
This is the 4.19-rc6 release
I needed to merge this in because of extensive conflicts in
the MSM and Intel pin control drivers. I know how to resolve
them, so let's do it like this.

any gpio mappings being configured that way so pdata->gpio_config

These codecs have a variable number of I/O lines each of which
is individually selectable to a wide range of possible functions.
The functionality is slightly different from the traditional muxed
GPIO since most of the functions can be mapped to any pin (and even
the same function to multiple pins). Most pins have a dedicated
"alternate" function that is only available on that pin. The
alternate functions are usually a group of signals, though it is
not always necessary to enable the full group, depending on the
alternate function and how it is to be used. The mapping between
alternate functions and GPIO pins varies between codecs depending
on the number of alternate functions and available pins.
