[PATCH] Staging: Silicom: bpctl_mod.c & bypass.c: Fixed a lot of checkpatch.pl warnings

From: Chaitanya Hazarey
Date: Sun May 25 2014 - 15:02:22 EST

Added a blank line after declarations in many places to fix the following warning issued by checkpatch.pl:

WARNING: Missing a blank line after declarations

Lets see if this works now, this patch is prepared against Greg's staging tree.
