Colin Ian King 85093a02be iio: tsl2583: Fix division by a zero lux_val ... commit af0e1871d7 upstream. The lux_val returned from tsl2583_get_lux can potentially be zero, so check for this to avoid a division by zero and an overflowed gain_trim_val. Fixes clang scan-build warning: drivers/iio/light/tsl2583.c:345:40: warning: Either the condition 'lux_val<0' is redundant or there is division by zero at line 345.
