From 0c3ae04b00f5664b98435b072c1694e62a823e5a Mon Sep 17 00:00:00 2001 From: Chris Lapa Date: Fri, 24 Jun 2016 12:26:07 +1000 Subject: [PATCH] max8903: store pointer to pdata instead of copying it. Stores pointer to pdata because it easily allows pdata to reference either platform data or in the future device tree data.
