Subject[PATCH 1/9] drivers: cdrom: fix horizontal whitespace
Date

This includes:
* Missing spaces around operators
* Removing trailing whitespace
* Removing whitespace from tabs
* Converting spaces to tabs
* Fixing wrong indentation

These whitespace errors were mainly reported
by scripts/checkpatch.pl
