Subject: [PATCH] xtensa: One function call less in bootmem_init()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 5 Jul 2019 18:33:58 +0200

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

This issue was detected by using the Coccinelle software.
