#1511027 — [PATCH 03/10] staging: iio: tsl2583: return proper error code instead of -1

taos_als_calibrate() has a code path where -1 is returned. This patch
changes the code so that a proper error code is returned.

Applied to the togreg branch of iio.git and pushed out as
testing for the autobuilders to play with it.
