[SRU Justification]
[Impact]
On a MIPI camera through Intel IPU6 platform that its raw V4L2 loopback interface is preserved for Intel Camera HAL libraries, a relay daemon + v4l2loopback is used to allow the usage of legacy V4L2 based apps.
v4l2loopback itself contains several potential issues that were identified by coverity tools. In order to prebuilt and sign this kernel module, these issues should be addressed first.
[Test Plan]
The changes here doesn't change the semantics of the implementation, and have no observable differences.
[Where problems could occur]
N/A.
[Other Info]
For Focal backports, 0.12.5-1 is equivalent to 0.12.3-1ubuntu0.3 plus micro version updates, so there should be little risk backport a new release, and we can drop additional patches carried. This implies bug 1905613.
This focal backport includes changes for bug 1921474, bug 1930208, and bug 1936250, so it will then become synced with Impish and newer again. The 0007-compliance-stop-declaring-V4L2_CAP_VIDEO_M2M-capabil.patch carried in bug 1930208 is deliberately skipped to avoid bug 1946660.
