From af64a7cb09db77344c596a0bf3d57d77257e8bf5 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Mon, 24 Feb 2014 19:59:58 +0100 Subject: ftrace: Pass retval through return in ftrace_dyn_arch_init() No architecture uses the "data" parameter in ftrace_dyn_arch_init() in any way, it just sets the value to 0. And this is used as a return value in the caller -- ftrace_init, which just checks the retval against zero. Note there is also "return 0" in every ftrace_dyn_arch_init. So it is enough to check the retval and remove all the indirect sets of data on all archs.
