[ Upstream commit aae7a2876c3b39d07aa7655ea082af8e7862f3a5 ] Unlike all the other allocations in this driver, the memory for storing the pin function descriptions allocated with kcalloc() and later resized with krealloc() is never freed. Use devres like elsewhere to handle that. While at it - replace krealloc() with more suitable devm_krealloc_array(). Note: the logic in this module is pretty convoluted and could probably use some revisiting, we should probably be able to calculate the exact amount of memory needed in advance or even skip the allocation altogether and just add each function to the radix tree separately.

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.
