[PATCH] pps: kc: fix non-tickless system config dependency

2016-03-05 Thread Maciej S. Szmigiero 
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.
