staging: skein: cleanup: add operator white space

This change “staging: skein: cleanup: add operator white space” (commit 78930e7) in Linux kernel is authored by Manu Kumar <maraku [at] gmx.com> on Mon Apr 4 16:53:01 2016 -0700.

Description of "staging: skein: cleanup: add operator white space"

The change “staging: skein: cleanup: add operator white space” introduces changes as follows.

staging: skein: cleanup: add operator white space

Added white space between operators and operands. Because this sometimes
maxed out the column width, some expressions were broken up into multiple
lines, and comments were moved appropriately.
