Subject: [PATCH stable 4.19 v2 4/4] ARM: 9098/1: ftrace: MODULE_PLT: Fix build problem without DYNAMIC_FTRACE

From: Alex Sverdlin <alexander.sverdlin@...ia.com>

commit 6fa630bf473827aee48cbf0efbbdf6f03134e890 upstream

FTRACE_ADDR is only defined when CONFIG_DYNAMIC_FTRACE is defined, the
latter is even stronger requirement than CONFIG_FUNCTION_TRACER (which is
enough for MCOUNT_ADDR).
