Subject: [PATCH 06/14] Regulators: tps6507x-regulator - mark probe method as __devinit
Date: Tue, 23 Feb 2010 23:38:12 -0800	[thread overview]
Message-ID: <20100224073811.15964.36760.stgit@localhost.localdomain> (raw)
In-Reply-To: <20100224073342.15964.8863.stgit@localhost.localdomain>

Also move error handling in probe() out of line and do not bother
to reset fields in structures that are about to be freed.
