The if-statement should be correctly indented (it's inside another
if-body, so needs to be one more tab over) and there needs to be a space
before the else.

You should probably split your printks up so they don't exceed 80 chars too,
for example:

printk(KERN_WARNING
"dev%d: Failed to create physical_node: %d\n",
status, pn);

Also 'status' is probably the wrong thing to print as the number in "dev%d".
If it worked, that should be unconditionally AE_OK, I think. Can you not use
dev_warn() or similar instead or printk?
