[PATCH v2 2/2] staging: iio: light: tsl2583.c: obsolete use of strict_strtoul

[Johannes Tenschert <Johannes.Tenschert@informatik.stud.uni-erlangen.de>]

The function strict_strtoul is obsolete and replaced by kstrtouint
and kstrtoint.

If kstrto* fails its return code is returned instead of -EINVAL.

Signed-off-by: Johannes Tenschert <Johannes.Tenschert@informatik.stud.uni-erlangen.de>
