[PATCH] EDAC/xgene: Use devm_platform_get_and_ioremap_resource() in xgene_edac_probe()

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.

[PATCH v2] EDAC/xgene: Use devm_platform_ioremap_resource() in xgene_edac_probe()

[Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>

A wrapper function is available since the commit 7945f929f1a77a1c8887a97ca07f87626858ff42
("drivers: provide devm_platform_ioremap_resource()").

* Thus reuse existing functionality instead of keeping duplicate source code.

* Delete a local variable which became unnecessary with this refactoring.


This issue was transformed by using the Coccinelle software.

v2:
The transformation pattern was adjusted based on advices by known contributors.

Examples:
