[PATCH] spi: fsl: Use kcalloc() in of_fsl_spi_get_chipselects()

From: Markus Elfring
Date: Fri Jan 13 2017 - 07:33:02 EST


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.
