Subject: [PATCH v3 1/3] driver: add flag to check if cdev is an mci device
Date: Mon, 10 May 2021 12:25:21 +0200 [thread overview]
Message-ID: <20210510102523.7147-1-m.felsch@pengutronix.de> (raw)
We need this during mount() to check if the cdev is an mmc/mci main|user
hardware partition device. Later on we add the feature to pass
"root=/dev/mmcblkXpN" as kernel command line.
Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>

v3:
