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

Markus Elfring (54):
  raid0: Use kcalloc() in create_strip_zones()
  raid0: Less function calls in create_strip_zones() after error detection
  raid0: Move a variable assignment in create_strip_zones()
  raid0: Replace printk() calls by the usage of higher level interfaces
  raid0: Move another variable assignment in create_strip_zones()
  raid0: Delete four unwanted spaces behind function names
  raid0: Move two misplaced braces
  raid0: Delete an unnecessary return statement in raid0_status()
  raid0: Add some spaces for better code readability
  raid1: Use kcalloc() in alloc_behind_pages()
  raid1: Use kcalloc() in raid1_reshape()
  raid1: Use kcalloc() in setup_conf()
  raid1: Return directly after a failed kzalloc() in setup_conf()
  raid1: Move assignments for the variable "err" in setup_conf()
