Please insert one line between the commit message and Signed-off-by.

Also, add '[PATCH]' to subject as follow:
     [PATCH] video: exynos_dp: Add device tree based discovery support

Last, pay attention of your mail address and name.
Um, now, you are using "~@samsung.com" as mail address and name.
Please configure your mail program in order to set "Ajay Kumar"
and "ajaykumar.rs@samsung.com".

If you want to get reviewed, please keep the basic rules
as I mentioned above.


Best regards,
Jingoo Han
