[PATCH 09/10] clk: ti: Less function calls in _ti_clkctrl_clk_register() after error detection

[Markus Elfring <Markus.Elfring@xxxxxx>]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sun, 24 Dec 2023 16:06:34 +0100

The kfree() function was called in a few cases by
the of_omap2_apll_setup() function during error handling
even if the passed variable contained a null pointer.

* Split a condition check.

* Adjust jump targets.
