Subject: [PATCH 03/29] l2tp: add a blank line following declarations
Date: Tue, 21 Jul 2020 18:31:55 +0100	[thread overview]
Message-ID: <20200721173221.4681-4-tparkin@katalix.com> (raw)
In-Reply-To: <20200721173221.4681-1-tparkin@katalix.com>

checkpatch likes an empty line following declarations, which gives a
visual prompt for where logic begins in a given block.

Add blank lines in l2tp code to adhere to this guideline.
