Claudiu Beznea bd433c25ca pinctrl: renesas: rzg2l: Fix locking in rzg2l_dt_subnode_to_map() 
Commit d3aaa7203a ("pinctrl: renesas: rzg2l: Add pin configuration
support for pinmux groups") introduced the possibility to parse pin
configuration for pinmux groups. It did that by calling
rzg2l_map_add_config() at the end of rzg2l_dt_subnode_to_map() and
jumping to the remove_group label in case rzg2l_map_add_config() failed.
But if that happens, the mutex will already be unlocked, thus this it will
lead to double mutex unlock operation. To fix this move the
rzg2l_map_add_config() call just after all the name argument is ready and
before the mutex is locked. There is no harm in doing this, as this only
parses the data from device tree that will be further processed by
pinctrl core code.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
