Subject: tile-module: Use kmalloc_array() in module_alloc()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8797fe75f164d4b2f183e776003612ece565c76e;p=openwrt%2Fstaging%2Fblogic.git

tile-module: Use kmalloc_array() in module_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 "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.
