From 47b91923ea41288751e83a5b080576085a831333 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 14 Sep 2015 11:32:47 +0300 Subject: [PATCH 1/2] mfd: intel-lpss: Fix build error when !CONFIG_PM_SLEEP Jim Davis reported the compilation error with a random configuration which apparently has CONFIG_PM=y and CONFIG_PM_SLEEP=n. With that conditions we have missed definition of INTEL_LPSS_SLEEP_PM_OPS macro. Add it here.
