From 69d5bbf073ee45f18492a6204dc25c934c6d3c05 Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Tue, 12 May 2020 15:46:16 -0700 Subject: espi_debug: Use switch case instead of if-else This change updates espi_debug.c to use switch case instead of if-else for operating frequency and i/o mode prints. This is done to address the review comments received on CB:41254.
