Two update suggestions were taken into account
from static source code analysis.

Markus Elfring (2):
  Use kcalloc() in ehv_bc_init()
  Fix a typo in two comment lines

* 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 structure by a pointer dereference
  to make the corresponding size determination a bit safer according to
  the Linux coding style convention.
