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. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>
