Subject: [PATCH 0/3] block: Deletion of checks before three function calls

From: Markus Elfring <elfring@...rs.sourceforge.net>

Functions which release a system resource are occasionally documented in the way
that they tolerate the passing of a null pointer for example. I do not see a need
because of this fact that a function caller repeats a corresponding check.

Markus Elfring (3):
  cciss: Deletion of an unnecessary check before the function call "put_disk"
  z2ram: Delete an unnecessary check before the function call "kfree"
  Deletion of checks before the function call "iounmap"
