[PATCH 9/9] staging: iio: tsl2583: remove redundant write to the control register in taos_probe()

From: Brian Masney
Date: Thu Nov 03 2016 - 08:58:18 EST


taos_probe() calls i2c_smbus_write_byte() to select the control
register, however there is no subsequent calls to i2c_smbus_read_byte().
The write call is unnecessary and is removed by this patch.

Verified that the driver still functions correctly using a TSL2581
hooked up to a Raspberry Pi 2.
