From 9ba93cb8212d62bccd8b41b8adb6656abf37280a Mon Sep 17 00:00:00 2001 From: Shyam Sundar S K Date: Wed, 5 Mar 2025 10:28:41 +0530 Subject: [PATCH] platform/x86/amd/pmf: Propagate PMF-TA return codes MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit In the amd_pmf_invoke_cmd_init() function within the PMF driver ensure that the actual result from the PMF-TA is returned rather than a generic EIO. This change allows for proper handling of errors originating from the PMF-TA.
