Subject: [PATCH 09/10] clk: ti: Less function calls in _ti_clkctrl_clk_register() after error detection
Date: Sun, 24 Dec 2023 17:50:42 +0100 [thread overview]
Message-ID: <b11039e4-69c6-4247-b4ba-c442b9427231@web.de> (raw)
In-Reply-To: <20849a8e-e0f5-46df-ad8a-9eae6cbe337b@web.de>
From: Markus Elfring <elfring@users.sourceforge.net>
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.
