[PATCH 39/70] staging:iio:light:tsl2x7x: fix the error handling in tsl2x7x_probe()

[Luis Henriques]

3.5.7.14 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Wei Yongjun <yongjun_wei at trendmicro.com.cn>

commit 3b813798aa7030f1beef638c75f8b0008f737a82 upstream.

Fix to return -EINVAL in the i2c device found error handling
case instead of 0, as done elsewhere in this function.
And also correct the fail1 and fail2 lable to do the right thing.
