Message-Id: <1468071929-77383-1-git-send-email-andriy.shevchenko@linux.intel.com> Date: Sat, 9 Jul 2016 16:45:29 +0300 From: Andy Shevchenko <andriy.shevchenko@...ux.intel.com> To: linux-kernel@...r.kernel.org, Thomas Gleixner <tglx@...utronix.de>, Ingo Molnar <mingo@...hat.com>, "H . Peter Anvin" <hpa@...or.com>, x86@...nel.org Cc: Andy Shevchenko <andriy.shevchenko@...ux.intel.com> Subject: [PATCH v1 1/1] x86/platform/intel-mid: Mark regulators explicitly defined Intel MID platforms are using explicitly defined regulators. Let 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.
