From 326b6adda0340f9de6da470906a5c262e2d738ff Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Fri, 23 Sep 2016 22:30:32 +0200 Subject: [PATCH] iio: Use kmalloc_array() in iio_scan_mask_set() commit 057ac1acdfc4743f066fcefe359385cad00549eb upstream. A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "kmalloc_array". This issue was detected by using the Coccinelle software.
