Subject: [PATCH 4/4] iio: auxadc: mediatek: change to subsys_initcall
Date: Thu, 16 May 2019 16:10:47 +0800
Message-ID: <1557994247-16739-5-git-send-email-chun-hung.wu@mediatek.com> (raw)
In-Reply-To: <1557994247-16739-1-git-send-email-chun-hung.wu@mediatek.com>

  Move auxadc platform_driver_register() from module_init
to subsys_initcall because auxadc user drivers
are all moudle drivers, need to gurantee
auxadc driver ready before module_init.
