* iio: tsl4531: fix error handling in tsl4531_check_id()Dan Carpenter2015-08-311-4/+5
| | | | | | | | | | | | | | The tsl4531_check_id() function returned 1 on "found" and 0 on "not found" and negative error codes on failure. This was non-standard and bug prone. The caller treated all non-zero values including error codes as "found". This patch fixes it by changing the tsl4531_check_id() to return zero on success or a negative error code, and updates the caller.

* iio: Add tsl4531 ambient light sensor driverPeter Meerwald2013-09-141-0/+258
driver for the TSL4531 family of 16-bit I2C ambient light sensors; information is here: http://www.ams.com/eng/Products/Light-Sensors/Ambient-Light-Sensor-ALS/TSL45315 the chip offers simple lux output v3 (thanks Lars-Peter Clausen): * add mutex to when updating integration time * fix chip ID checking * code cleanups v2: * rename to tsl4351 * use INT_TIME Signed-off-by: Peter Meerwald <pmeerw@pmeerw.net> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
