points it mentions were already tackled. In addition it is no longer
considered relevant to wait for a stateless encoder driver to move it out
of staging. The hantro/verisilicon driver was already unstaged without this
condition.

However the driver suffers from a bad initial design that showed to be very
limiting. It was also not a very good fit for a video codec driver either.

Since a rework of the driver was already carried out for the purpose of
adding encoding support, update the TODO list with a description of the
rework. This reworked driver will be published soon and transitional
commits from the current driver will be submitted upstreamer after that.

It seems best to wait for the rework to land upstream before unstaging the
driver, since a major rework is best operated on a staging driver instead
of a fully upstream one.

media: core: v4l2-ioctl: check if ioctl is known to avoid NULL name

When ioctl debugging is turned on, the v4l_printk_ioctl() is used
to log the ioctl that is called. It uses an array of ioctl information
to log the ioctl name and it correctly checks for out-of-bound indexing
of that array. However, the array may have holes since not all ioctl
numbers are used. In that case the name of the ioctl is NULL.

It is harmless (printk handles NULL pointers), but not intended. Instead
use the v4l2_is_known_ioctl() function to determine if the ioctl
information is available or not.
