Staging: iio/accel: Changed return type of lis3l02dq_read_event_config() to int
The lis3l02dq_read_event_config() function returned an ssize_t up to now, which lead to a compiler warning in line 660 (initialization from incompatible pointer type). The iio_info struct is defined to accept an int-returning function as the read_event_config parameter. Also it seems odd to have the check for (ret < 0) and return ret in this case, when the return type is signed.
