[PATCH 1/6] clk: hisilicon: Use kcalloc() in hisi_clk_init()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>

* A multiplication for the size determination of a memory allocation
  indicated that an array data structure should be processed.
  Thus use the corresponding function "kcalloc".

  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.
