Subject[PATCH v2 3/4] pps: Use subdir-ccflags-* to inherit debug flag
Date
From: Junhao He <hejunhao2@hisilicon.com>

We use ccflags-$(CONFIG_PPS_DEBUG) for the debug
message in drivers/pps, but the DEBUG flag will not pass to
the subdirectory.

Considering CONFIG_HWMON_DEBUG_CHIP intends to turn on debug
recursively under driver/pps, so it will be clearer to use
subdir-ccflags-* instead of ccflags-* to inherit
the debug settings from Kconfig when traversing subdirectories.
