Latest commit broke dma-proxy-test

[jr4417]

Changes to dma-proxy.c in the latest commit have broken the dma-proxy-test. For instance line (436):

if (!local_class_p) {
local_class_p = class_create(
#if LINUX_VERSION_CODE <= KERNEL_VERSION(6, 3, 13)
THIS_MODULE,
#endif
DRIVER_NAME
);
pchannel_p->class_p = local_class_p; <--------This line (436) needs to move after the if(!local_class_p) statement
if (IS_ERR_OR_NULL(local_class_p)) {
dev_err(pchannel_p->dma_device_p, "unable to create class\n");
if(!local_class_p) {
return -ENOMEM;
} else {
return ERR_PTR(local_class_p);
}
goto init_error2;
}
}

This line does not allow for a second device to be added to the /dev/ folder. After moving this outside of the if the second device was able to be created. The dma-proxy-test still did not work. I had to go back to the 6060d20 commit and the test worked.
