From: Markus Elfring Date: Sat, 10 Sep 2016 06:02:06 +0000 (+0200) Subject: ATM-nicstar: Use kmalloc_array() in get_scq() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=78706121d59d0692534d087df6eefef5469fc5a1;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ATM-nicstar: Use kmalloc_array() in get_scq() * 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 type by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention.
