[PATCH] s390/cpum_cf: Use kmalloc_array() in merge_attr()
From: Markus ElfringDate: Sat, 3 Sep 2016 15:17:45 +0200 * A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus reuse the corresponding function "kmalloc_array". * 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.
