From 3190ba863daecf6ac9300f57beb8c7eae74b8c50 Mon Sep 17 00:00:00 2001 From: Martin Roth Date: Thu, 5 Nov 2020 11:20:19 -0700 Subject: soc/amd/common: Don't program GPIOs if the table isn't set Currently, there's no check for the table being programmed. This skips programming a table if the table size is zero, or the pointer to the table has been set to NULL. BUG=None TEST=Set table pointer to NULL, table doesn't run.
