Subject: [PATCH 02/10] scsi: 53c700: Trivial: Remove trailing whitespace

Since 5a602de99797b ("Add .editorconfig file for basic formatting") my
editor has been forced to remove trailing whitespace from any file it
saves.  Instead of fighting this recent kernel default, let's start
chipping away at fixing the issues.
