From 9a7f6a4c6edc84748c6477c9df56691a0e61b8fd Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 11 Feb 2010 17:22:45 +0000 Subject: [PATCH] regulator: Assume regulators are enabled if they don't report anything If a regulator driver does not provide a way to query if the driver is enabled then assume that it is enabled. This is very likely to reflect the actual state is more useful for callers than reporting an error.
