From: Mario Limonciello <mario.limonciello@amd.com> stable inclusion from stable-v6.6.13 commit a7edb661bb85d9e944ede51554b54f74a07af8d9 bugzilla: https://gitee.com/openeuler/kernel/issues/I99TJK Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ 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.
