Subject: [for-next][PATCH 24/34] ftrace: Use true and false for boolean values in ops_references_rec()

From: "Gustavo A. R. Silva" <gustavo@...eddedor.com>

Return statements in functions returning bool should use true or false
instead of an integer value.

This code was detected with the help of Coccinelle.
