A patch from Markus Elfring has be queued:

commit a68b931932c5574aa5bd459529c766ba577c72b3
Author: Markus Elfring <elfring@...rs.sourceforge.net>
Date:   Wed Sep 18 09:09:22 2019 +0200

    hwrng: iproc-rng200 - Use devm_platform_ioremap_resource() in iproc_rng200_probe()

    Simplify this function implementation by using a known wrapper function.

    This issue was detected by using the Coccinelle software.
