looks like libimxdmabuffer do not sipport newer Linux versions:

Please provide more details on how to reproduce the issue. What machine are you using and which branches are involved?

[carlosgonz0]

Branch is this: https://github.com/Freescale/libimxdmabuffer/releases/tag/1.1.3 i tryed master too. Machine is this: Librem 5 and Linux 6.6.92: https://source.puri.sm/Librem5/linux
