Arvind Yadav 3282fa3c0a iio: light: tsl2583: constify i2c_device_id
i2c_device_id are not supposed to change at runtime. All functions
working with i2c_device_id provided by <linux/i2c.h> work with
const i2c_device_id. So mark the non-const structs as const.

Brian Masney 371894f5d1 iio: tsl2583: add runtime power management support
This patch adds runtime power management support to the tsl2583 driver.
The device is powered off after two seconds of inactivity. Verified that
the driver still functions correctly using a TSL2581 hooked up to a
Raspberry Pi 2.

Dan Carpenter 0e8d2b0f74 iio: tsl2583: make array large enough
This array is supposed to have 10 elements.  Smatch complains that with
the current code we can have n == max_ints and read beyond the end of
the array.
