From be24c270185930997b55e20a859a954b2f4eaa46 Mon Sep 17 00:00:00 2001 From: Jeffrey Hugo Date: Sat, 16 Feb 2019 22:05:52 -0700 Subject: tty: serial: msm_serial: Remove __init from msm_console_setup() Due to the complexities of modern Qualcomm SoCs, about a half dozen drivers must successfully probe before the clocks for the console are present, and the console can successfully probe. Depending on several random factors such as probe order and modules vs builtin, msm_serial may not be able to successfully probe for some, at which point, __init annotated functions may become unmapped. If this occurs, msm_console_setup() will be called from the probe path, but will no longer exist, resulting in a kernel panic. Resolve this issue by removing the __init annotation from msm_console_setup().
