From 781de7ade6c3ccc5efca9c635d64c1c07427a6d1 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Tue, 18 Apr 2017 10:30:04 +0200 Subject: [PATCH] clk: hi3620: Use kcalloc() in hi3620_mmc_clk_init() * 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. * 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.
