Subject: [PATCH v4 2/7] max8903: store pointer to pdata instead of copying it.
Date: Mon, 20 Jun 2016 08:27:17 +1000 [thread overview]
Message-ID: <1466375242-38354-3-git-send-email-chris@cpdesign.com.au> (raw)
In-Reply-To: <1466375242-38354-1-git-send-email-chris@cpdesign.com.au>
In-Reply-To: <1464849897-21527-3-git-send-email-chris@lapa.com.au>
From: Chris Lapa <chris@lapa.com.au>
Stores pointer to pdata because it easily allows pdata to reference
either platform data or in the future device tree data.
