2020-12-08drm/mediatek: avoid dereferencing a null hdmi_phy on an error messageColin Ian King
Currently there is a null pointer check for hdmi_phy that implies it may be null, however a dev_err messages dereferences this potential null pointer. Avoid a null pointer dereference by only emitting the dev_err message if hdmi_phy is non-null. It is a moot point if the error message needs to be printed at all, but since this is a relatively new piece of code it may be useful to keep the message in for the moment in case there are unforseen errors that need to be reported.

This driver includes the following two files directly: - mt7621.h - ralink_regs.h Compilation for its related platform properly works because its real path is included in 'arch/mips/ralink/Platform' as cflags. This driver depends on RALINK but also is enabled for COMPILE_TEST where nothing about its platform is known and this directly included files are not found at all breaking compilation. If we want 'COMPILE_TEST' we have to change cflags also inside 'phy/ralink' subdirectory Makefile which seems that does not like to linux-phy maintainers. Hence remove COMPILE_TEST from Kconfig to avoid the problem.

In commit "phy: tegra: xusb: Add usb-phy support", an OTG capable PHY device, such as phy-usb2.0 device of Jetson-TX1 platform, will be bound to the tegra-xusb-padctl driver by the following line in tegra_xusb_setup_usb_role_switch(). port->usb_phy.dev->driver = port->padctl->dev->driver; With this, dev_pm_ops set of tegra-xusb-padctl driver will be invoked for the OTG capable PHY incorrectly as below logs show. This commit fixes the issue by assigning an empty driver to it.

Initially this PHY driver was implementing MDIO access on its own. It was caused by lack of proper hardware design understanding. It has been changed back in 2017. DT bindings were changed and driver was updated to use MDIO layer. It should be really safe now to drop the old deprecated code. All Linux stored DT files don't use it for 3,5 year. There is close to 0 chance there is any bootloader with its own DTB using old the binding.
