From ab47deb6bb03ddf1c1e253bfbbdbf5f867975ca5 Mon Sep 17 00:00:00 2001 From: "Maciej S. Szmigiero" Date: Tue, 11 Oct 2016 13:54:30 -0700 Subject: [PATCH] pps: kc: fix non-tickless system config dependency CONFIG_NO_HZ currently only sets the default value of dynticks config so if PPS kernel consumer needs periodic timer ticks it should depend on !CONFIG_NO_HZ_COMMON instead of !CONFIG_NO_HZ. Otherwise it is possible to enable it even on tickless system which has CONFIG_NO_HZ not set and CONFIG_NO_HZ_IDLE (or CONFIG_NO_HZ_FULL) set.
