From a11836fa5a67ba56d8338138e37b42384af73e5e Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Sat, 9 Jul 2016 16:45:29 +0300 Subject: x86/platform/intel-mid: Mark regulators explicitly defined Intel MID platforms are using explicitly defined regulators. Let the regulator core know that we do not have any additional regulators left. This lets it substitute unprovided regulators with dummy ones. Without this change when CONFIG_REGULATOR=y the USB driver fails on getting "vbus" regulator and SDHCI can't get "vmmc" and "vqmmc" regulators either.
