From 9dd3f1ef40d01fdfe69c3ada28b1f201a7207f6e Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Thu, 28 Dec 2023 09:30:54 +0100 Subject: [PATCH] platform/x86/amd/pmf: Return directly after a failed apmf_if_call() in apmf_sbios_heartbeat_notify() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The kfree() function was called in one case by the apmf_sbios_heartbeat_notify() function during error handling even if the passed variable contained a null pointer. This issue was detected by using the Coccinelle software. * Thus return directly after a call of the function “apmf_if_call” failed at the beginning. * Delete the label “out” which became unnecessary with this refactoring.
