From 8d9bdc46c780325414af7f09827c78c69f9b1e3d Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Tue, 18 Apr 2017 10:15:19 +0200 Subject: [PATCH] clk: hisilicon: Use devm_kmalloc_array() in hisi_clk_alloc() * A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "devm_kmalloc_array". 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.
