From a7edb661bb85d9e944ede51554b54f74a07af8d9 Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Mon, 11 Dec 2023 22:50:04 -0600 Subject: [PATCH] platform/x86/amd/pmc: Only run IRQ1 firmware version check on Cezanne MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit [ Upstream commit 2d53c0ab61e62302d7b62d660fe76de2bff6bf45 ] amd_pmc_wa_czn_irq1() only runs on Cezanne platforms currently but may be extended to other platforms in the future. Rename the function and only check platform firmware version when it's called for a Cezanne based platform.
