Subject: [PATCH v2 2/4] hwmon: Use subdir-ccflags-* to inherit debug flag
Date: Tue, 9 Feb 2021 19:08:17 +0800	[thread overview]
Message-ID: <1612868899-9185-3-git-send-email-yangyicong@hisilicon.com> (raw)
In-Reply-To: <1612868899-9185-1-git-send-email-yangyicong@hisilicon.com>

From: Junhao He <hejunhao2@hisilicon.com>

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

Considering CONFIG_HWMON_DEBUG_CHIP intends to have DEBUG
recursively in driver/hwmon. It will be clearer
to use subdir-ccflags-* instead of ccflags-* to inherit
the debug settings from Kconfig when traversing subdirectories,
and it will avoid omittance of DEBUG define when debug messages
added in the subdirectories.
