From 32e5deac3627a508f43806788dafa933b51d5d46 Mon Sep 17 00:00:00 2001 From: Ivaylo Dimitrov Date: Sat, 26 Mar 2016 10:28:15 +0200 Subject: regulator: twl: Regulator mode should not depend on regulator enabled state When machine constraints are applied, regulator framework first sets initial mode (if any) and then enables the regulator if needed. The current code in twl4030reg_set_mode always checks if the regulator is enabled before applying the mode. That results in -EACCES error returned for "always-on" regulators which have "initial-mode" set in the board DTS. Fix that by removing the unneeded check.
