From 797236f10a095a1742373bca5f284c5ec8afb446 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Fri, 13 Jan 2017 14:30:43 +0100 Subject: [PATCH] spi/ppc4xx: Use kcalloc() in spi_ppc4xx_of_probe() * 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. * Replace the specification of a data type by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention.
