From b96244fad9530a707b732c3650d349aed2c9cfcd Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Fri, 21 Mar 2014 16:16:24 +0800 Subject: [PATCH] regulator: s2mps11: Don't check enable_shift before setting enable ramp rate Current code misses updating the register when enable_shift is 0. e.g. S2MPS11_BUCK9_RAMP_SHIFT and S2MPS11_BUCK6_RAMP_EN_SHIFT are 0.
