From: Per Forlin <perfn@xxxxxxxx>
If the disk has no write cache the following errors are being logged.
* sd 1:0:0:0: [sdb] No Caching mode page found
* sd 1:0:0:0: [sdb] Assuming drive cache: write through
Lower the severity from error to info.
The absence of a write cache should not be treated as an error.
There are many portable drives that don't have a write cache.
