Subject: [PATCH 2/2 v2 net-next] lib8390: Fix coding-style issues and remove
 verion printing

Fix various checkpatch warnings.

Remove version printing so modules including lib8390 do not
have to provide a global version string for successful
compilation.

Replace pr_cont() with SMP-safe construct.
