[PATCH] mfd: ntxec: Change return type of ntxec_reg8 from __be16 to u16

[PATCH] mfd: ntxec: Change return type of ntxec_reg8 from __be16 to u16

[Jonathan Neuschäfer]

Register values in NTXEC are big-endian on the I2C bus, but the regmap
subsystem handles the conversion between CPU-endian and big-endian data
internally. ntxec_reg8 should thus return u16, not __be16.
