Subject: [PATCH v4 4/6] iio: light: stk3310: use dev_err_probe where possible
Using dev_err_probe instead of dev_err and return makes the errors
easier to understand by including the error name, and saves a little
code.
Signed-off-by: Aren Moynihan <aren@...cevolution.org>

Notes:
Changes in v4:
- Get a struct device ahead of time so it can be passed as "dev"
instead of "&client->dev"
No changes in v3
Added in v2
