[PATCH] interconnect: imx: Reduce scope for the variable “dn” in imx_icc_node_init_qos()

[Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Sun, 6 Dec 2020 17:57:19 +0100

A local variable was used only within a single else branch.
Thus move the definition for the variable “dn” into the corresponding
code block.

This issue was detected by using the Coccinelle software.
