[ Upstream commit 07c7c640a8eb9e196f357d15d88a59602a947197 ]
Make sure to unmap and release the component iomap and clock on probe
failure (e.g. probe deferral) and on driver unbind.
Note that unlike of_iomap(), devm_of_iomap() also checks whether the
region is already mapped.

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.
