Subject: [PATCH] platform/x86/amd/pmc: Only run IRQ1 firmware version check on Cezanne
Mime-version: 1.0
Content-type: text/plain; charset=UTF-8
Content-transfer-encoding: 8bit
Git-commit: 2d53c0ab61e62302d7b62d660fe76de2bff6bf45
Patch-mainline: v6.7-rc7
References: git-fixes
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.
