Subject: ieee1394: eth1394: coding style
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=efbeccf174bac803421a5f35076a17af47c9ce00;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

ieee1394: eth1394: coding style

Adjust white space and line wraps.  Remove unnecessary parentheses and
braces, unused macros, and some of the more redundant comments.
