commit21144298(power: twl6035: add palmas PMIC support) introduced twl6035_i2c_[read|write]_u8 Then, commitdd23e59d(omap5: pbias ldo9 turn on) introduced palmas_[read|write]_u8 for precisely the same access function. TWL6035 belongs to the palmas family, so instead of having an twl6035 API, we could use an generic palmas API instead. To stay consistent with the function naming of twl4030,6030 accessors, we use palmas_i2c_[read|write]_u8 Cc: Balaji T K <balajitk@ti.com> Cc: Sricharan R <r.sricharan@ti.com> Reported-by: Ruchika Kharwar <ruchika@ti.com> Signed-off-by: Nishanth Menon <nm@ti.com>
