From 1b1c26b24a6e75d96967515e55fba6c9954d4009 Mon Sep 17 00:00:00 2001 From: Matti Vaittinen Date: Mon, 20 Jan 2020 15:42:38 +0200 Subject: mfd: Rohm PMICs: Use platform_device_id to match MFD sub-devices Thanks to Stephen Boyd I today learned we can use platform_device_id to do device and module matching for MFD sub-devices! Do device matching using the platform_device_id instead of using explicit module_aliases to load modules and custom parent-data field to do module loading and sub-device matching.
