From b38dd0e8edd0ccd28eaa67a76e7d10ec693ce3a3 Mon Sep 17 00:00:00 2001 From: Jeffy Chen Date: Tue, 18 Jul 2017 14:02:55 +0800 Subject: [PATCH] serial: omap: Remove __init marking from early write The earlycon would be alive outside the init code in these cases: 1/ we have keep_bootcon in cmdline. 2/ we don't have a real console to switch to. So remove the __init marking to avoid invalid memory access.
