From 63928d4789ebb3f7d35d9261089b3bcc98ae0632 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Sun, 8 Jan 2017 22:10:40 +0100 Subject: [PATCH] mmc: core: Use kmalloc_array() in mmc_alloc_sg() * 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. * Replace the specification of a data structure by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention.
