[PATCH v4 03/11] Input: stmfts - Switch to devm_regulator_bulk_get_const

[David Heidelberg via B4 Relay <devnull+david.ixit.cz@kernel.org>]

From: David Heidelberg <david@ixit.cz>

Switch to devm_regulator_bulk_get_const() to stop setting the supplies
list in probe(), and move the regulator_bulk_data struct in static const.
