Subject: [PATCH 3/3] ARM: orion5x: ts78xx debugging changes
Date: Sat, 14 Apr 2012 19:00:54 +0100	[thread overview]
Message-ID: <1334426454-3206-4-git-send-email-alex@digriz.org.uk> (raw)
In-Reply-To: <1334426454-3206-1-git-send-email-alex@digriz.org.uk>

Moved to using a redefined pr_fmt to spare having to manually
prefix every message line with 'ts78xx'.
