From: Mark Brown Date: Tue, 30 Jan 2018 12:16:31 +0000 (+0000) Subject: regulator: Fix suspend to idle X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=57a0dd187956ea04870f4bbbf25a63c425ee7cad;p=openwrt%2Fstaging%2Fblogic.git regulator: Fix suspend to idle When suspending to idle with the new suspend mode configuration support we go through the suspend callbacks with a state of PM_SUSPEND_TO_IDLE which we don't have regulator constraints for, causing an error. Avoid this and similar errors by treating missing constraints as a noop.
