Subject: [PATCH] iommu/ipmmu-vmsa: Use
 devm_platform_get_and_ioremap_resource() in ipmmu_probe()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 5 Feb 2024 11:36:51 +0100

A wrapper function is available since the commit 890cc39a879906b63912482dfc41944579df2dc6
("drivers: provide devm_platform_get_and_ioremap_resource()").
Thus reuse existing functionality instead of keeping duplicate source code.

This issue was detected by using the Coccinelle software.
