[RESEND PATCH v8 1/5] mfd: tps65218: Remove redundant read wrapper
From: Keerthy <j-keerthy@ti.com>
Date: 2016-10-17 16:00:05
Also in:
linux-devicetree, linux-gpio, linux-omap, lkml
Subsystem:
gpio subsystem, multifunction devices (mfd), omap2+ support, the rest, voltage and current regulator framework · Maintainers:
Linus Walleij, Bartosz Golaszewski, Lee Jones, Aaro Koskinen, Andreas Kemnade, Kevin Hilman, Roger Quadros, Tony Lindgren, Linus Torvalds, Liam Girdwood, Mark Brown
Currently read directly calls the repmap read function. Hence remove the redundant wrapper and use regmap read wherever needed.
