Subject: [PATCH] mfd: asic3: One function call less in asic3_irq_probe()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 5 Jul 2019 20:22:26 +0200

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

This issue was detected by using the Coccinelle software.
