Date: Tue, 11 Dec 2012 20:36:37 +0800 From: Axel Lin <axel.lin@...ics.com> To: Mark Brown <broonie@...nsource.wolfsonmicro.com> Cc: Marek Szyprowski <m.szyprowski@...sung.com>, Liam Girdwood <lrg@...com>, linux-kernel@...r.kernel.org Subject: [PATCH] regulator: core: Fix logic to determinate if regulator can change voltage Having a linear_min_sel setting means the first linear_min_sel selectors are invalid. We need to subtract linear_min_sel when use n_voltages to determinate if regulator can change voltage.
