Subject: [PATCH] misc: apds9802als: Fix the logic checking timeout in
 als_wait_for_data_ready()

In the case of timeout waiting for data ready, the retry variable is -1.
This also fixes a bug: current code returns -ETIMEDOUT if latest retry success
( which means retry is 0 when exiting the while loop ).
