insmod axidma.ko doesn't create character device in /dev/axidma #160

Hello, I'm using a Kria KV260 with ubuntu 22.04 LTS, after solving compiler errors with solutions from other issues such as #123, I compile the driver without any errors and input the insmod command, typing dmesg | grep "axidma" gives a message about tainting the kernel which, after some googling, turned out to be just a warning. When I compile the examples and try to run axidma_benchmark it says dev/axidma file not found (I am very sorry as I cannot provide the exact wording of the error at the moment). When I try to run the insmod command again, it says file already present.
