[GIT PULL][PATCH] sh: ftrace: Fix missing parenthesis in WARN_ON()

From: Steven Rostedt
Date: Thu Jan 03 2019 - 22:26:04 EST


It appears that the zero-day bot did find a bug in my sh build.
And that I didn't have the bad code in my config file when I
cross compiled it, although there are a few other errors in sh
that makes it not build for me, I missed that I added one more.

I replaced WARN_ON(current->curr_ret_stack) with
WARN_ON(ftrace_graph_get_ret_stack(current, 1) where it should be:
WARN_ON(ftrace_graph_get_ret_stack(current, 1))

sh: ftrace: Fix missing parenthesis in WARN_ON()

Adding a function inside a WARN_ON() didn't close the WARN_ON parathesis.
