Subject: [PATCH 1/2] [media] blackfin-capture: Use kcalloc() in
 bcap_init_sensor_formats()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 9 Oct 2016 21:12:13 +0200

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

This issue was detected by using the Coccinelle software.
