Hi,
I would like to once again request backporting 5326ab737a47 ("virtio_console: fix order of fields cols and rows") to LTS kernels (6.12.x, 6.6.x, 6.1.x, 5.15.x and 5.10.x). The patch fixes a discrepancy between the Virtio spec and the Linux implementation.
Previously, we were considering changing the spec instead, however, a decision has been made [1] to keep the spec and backport the kernel fix.

I'm working on QEMU patches that add virtio console size support. Without the fix, rows and columns will be swapped.
As far as I know, there are no device implementations that use the wrong order and would by broken by the fix.
Note: A previous version [1] of the patch contained "Cc: stable" and "Fixes:" tags, but they seem to have been accidentally left out from the final version.
