No, it is intentional.
In the exynos_dp_video_phy_probe(), only devm_*() are called as below.
devm_kzalloc(),
devm_ioremap_resource(),
devm_of_phy_provider_register(),
devm_phy_create(),
Also, dev_set_drvdata(dev, NULL), phy_set_drvdata(state->phys, NULL) are not necessary in remove(), because driver core clears automatically after device_release.
Thus, there is no functions in the remove().
Thank you for your comment. :)
It is very helpful.
Best regards,
Jingoo Han

Yes, makes sense. There are quite a few various PHYs on the Exynos SoC. Let me resend my series with the binding description file name changed to samsung-phy.txt. I need to add couple fixes to that series anyway.
