[ Upstream commit d7faa8ffb6 ]
In function rockchip_dt_node_to_map, a new_map variable is
allocated by:
new_map = devm_kcalloc(pctldev->dev, map_num, sizeof(*new_map),
GFP_KERNEL);
This uses devres and attaches new_map to the pinctrl driver.
This cause a leak since new_map is not released when the probed
driver is removed. Fix it by using kcalloc to allocate new_map
and free it in `rockchip_dt_free_map`

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
