If anyone has any objections, please let me know. ------------------ From: Isaac Scott [ Upstream commit 5a6a461079decea452fdcae955bccecf92e07e97 ] Previously, the ad5398 driver used only platform_data, which is deprecated in favour of device tree. This caused the AD5398 to fail to probe as it could not load its init_data. If the AD5398 has a device tree node, pull the init_data from there using of_get_regulator_init_data.
