Since i2c_unregister_device() became NULL-aware we may remove duplicate
NULL check.

Kieran Bingham b0fe777884 media: i2c: adv748x: Store the pixel rate ctrl on CSI objects
The current implementation has to search the list of controls for the
pixel rate control, each time it is set.  This can be optimised easily
by storing the ctrl pointer in the CSI/TX object, and referencing that
directly.

While at it, fix up a missing blank line also highlighted in review
comments.

Simon Yuan bc66c99a7e [media] media: i2c: adv748x: Map v4l2_std_id to the internal reg value
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.

Javier Martinez Canillas 61e220adf6 media: i2c: adv748x: Export I2C device table entries as module aliases
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

Kieran Bingham 3e89586a64 media: i2c: adv748x: add adv748x driver
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.
