From 0561155f6fc5d4e3702b3805fea0ec1f55e5f08e Mon Sep 17 00:00:00 2001 From: Brian Masney Date: Thu, 3 Nov 2016 08:56:16 -0400 Subject: [PATCH] staging: iio: tsl2583: don't shutdown chip when updating the lux table in_illuminance_lux_table_store() shuts down the chip, updates the contents of the lux table, and then turns the chip back on. The values in lux table are not used by the chip and are only used internally by the driver. It is not necessary to change the power state on the chip. This patch removes the calls to taos_chip_off() and taos_chip_on() in in_illuminance_lux_table_store().
