From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx> Date: Sun, 24 Dec 2023 09:40:10 +0100 The kfree() function was called in one case by the stm32f4_rcc_init() function during error handling even if the passed variable contained a null pointer. This issue was detected by using the Coccinelle software. Thus use another label.
