Subject: [PATCH] irqchip/qcom-mpm: Replace devm_kasprintf() call by
 devm_kstrdup() in qcom_mpm_init()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 16 Apr 2025 15:43:46 +0200

Use a devm_kstrdup() call instead of a devm_kasprintf() call
in this function implementation because only a single string
should be copied.

The source code was transformed by using the Coccinelle software.
