[PATCH] clk: renesas: mstp: Delete an unnecessary kfree() call in cpg_mstp_clocks_init()

[Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Tue, 27 Aug 2019 15:22:12 +0200

A null pointer would be passed to a call of the function “kfree”
directly after a call of the function “kzalloc” failed at one place.
Remove this superfluous function call.

This issue was detected by using the Coccinelle software.
