Subject: [PATCH] ethernet: wiznet: Use
 devm_platform_get_and_ioremap_resource() in w5300_hw_probe()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 5 Feb 2024 14:22:32 +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.
