Subject: [PATCH] coresight: etm4x: Two function calls less

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 5 Jul 2019 19:33:26 +0200

Avoid an extra function call in two function implementations
by using a ternary operator instead of a conditional statement.

This issue was detected by using the Coccinelle software.
