From b5067f8ff37ed6cfa024170a9819bb09d55e9c1f Mon Sep 17 00:00:00 2001 From: David Brownell Date: Sat, 13 Oct 2007 23:56:30 +0200 Subject: [PATCH] i2c/tps65010: New-style driver updates, part 1 Prepare to convert tps65010 driver to "new style" driver by changing how it references the i2c_client. This lets the eventual patch with driver and platform updates be smaller.
