Subject: [PATCH v2 2/2] iio: temperature: tmp006: Add OF device matching
 support

Adds an of_device_id table entry to the driver, enabling
device matching through device tree. With this update, the driver
can now match devices using both the i2c_device_id entry and the
newly added of_device_id table.

Signed-off-by: Anup Sharma <anupnewsmail@...il.com>

---
Changes:
V1 -> V2: Keep the exsisting MODULE_DEVICE_TABLE entry.
	  Removed the inner comma in of_device_id.
	  Order the included header to improve code organization.
