Bug Description

SRU Justification

[Impact]

v4l2loopback-dkms cannot be installed because CONFIG_MEDIA_CAMERA_SUPPORT is disabled.
Amazon would like this feature enabled. It is already enabled in the Groovy and Hirsute AWS kernels.

[Fix]

CONFIG_MEDIA_CAMERA_SUPPORT=y

[Test Case]

sudo apt-get install v4l2loopback-dkms

[Where problems could occur]

Enabling ioctl functionality in the kernel could expose security vulnerabilities.

[Other Info]
SF: #00309464

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
