The video standard was not mapped to the corresponding value of the
internal video standard in adv748x_afe_querystd, causing the wrong
video standard to be selected.

The I2C core always reports a MODALIAS of the form i2c:<foo> even if the
device was registered via OF, and the driver is only exporting the OF ID
table entries as module aliases.
So if the driver is built as module, autoload won't work since udev/kmod
won't be able to match the registered OF device with its driver module.
Before this patch:
$ modinfo drivers/media/i2c/adv748x/adv748x.ko | grep alias
alias: of:N*T*Cadi,adv7482C*
alias: of:N*T*Cadi,adv7482
alias: of:N*T*Cadi,adv7481C*
alias: of:N*T*Cadi,adv7481
After this patch:
modinfo drivers/media/i2c/adv748x/adv748x.ko | grep alias
alias: of:N*T*Cadi,adv7482C*
alias: of:N*T*Cadi,adv7482

Provide support for the ADV7481 and ADV7482.
The driver is modelled with 4 subdevices to allow simultaneous streaming
from the AFE (Analog front end) and HDMI inputs though two CSI TX
entities.
The HDMI entity is linked to the TXA CSI bus, whilst the AFE is linked
to the TXB CSI bus.
The driver is based on a prototype by Koji Matsuoka in the Renesas BSP,
and an earlier rework by Niklas Söderlund.
