[PATCH] Input: twl6040-vibra - use devm_regulator_bulk_get()

[PATCH] Input: twl6040-vibra - use devm_regulator_bulk_get()

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@freescale.com>

Using devm_regulator_bulk_get() can make the code cleaner and smaller as we
do not need to call regulator_bulk_free() in the error and remove paths.

Can we complete the conversion and use devm_input_allocate_device() as
well?

Thanks.
