Subject: [PATCH v6 1/6] mfd: tps65218: Remove redundant read wrapper
Currently read directly calls the repmap read function. Hence
remove the redundant wrapper and use regmap read wherever
needed.
Acked-by: Lee Jones <lee.jones@...aro.org>
Signed-off-by: Keerthy <j-keerthy@...com>
---
Changes in v6:
Rebased against linux-next + https://lkml.org/lkml/2016/6/24/122 series.
Changes in v4:
* Added Lee Jones's Ack.
Changes in v3:
* Cleaned up tps65218-pwrbutton and gpio drivers to remove
tps65218_reg_read instances.
