From 55bb5193cec58f8ffb73df6b8feb0d4b0ada53f4 Mon Sep 17 00:00:00 2001 From: Vignesh Raghavendra Date: Wed, 11 Nov 2020 16:56:52 +0530 Subject: [PATCH] serial: 8250: 8250_omap: Fix possible array out of bounds access commit d4548b14dd7e5c698f81ce23ce7b69a896373b45 upstream. k3_soc_devices array is missing a sentinel entry which may result in out of bounds access as reported by kernel KASAN. Fix this by adding a sentinel entry.
