[PATCH 1/2] tty-goldfish: Use kcalloc() in goldfish_tty_create_driver()

[SF Markus Elfring <elfring@users.sourceforge.net>]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Tue, 11 Apr 2017 20:00:23 +0200

A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "kcalloc".

This issue was detected by using the Coccinelle software.
