Subject: [PATCH 01/17] spi: Use kcalloc() in spi_register_board_info()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 13 Jan 2017 12:28:04 +0100

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.
