[PATCH 1/1] [media] s5k6aa: Use devm_regulator_bulk_get API

[Sachin Kamat]

devm_regulator_bulk_get is device managed and saves some cleanup
and exit code.

Applied to my tree for 3.9, thanks.

I had some doubts initially, since this driver ideally needs to have
regulator_bulk_enable/disable function calls replaced with explicit
regulator_enable/regulator_disable calls, to ensure proper voltage
regulator enable/disable sequence (the bulk API doesn't guarantee
any specific sequence).

But this patch is just about regulator_get/regulator_put and it looks
fine.
