Message:

dsrlnout_init() needs to get physical address too

The IO address we are passing into dsrlnout_init() should not be a
kernel-identity virtual address, because the device memory should not be
cacheable. Therefore, the function cannot use KA2PA to translate it
back to physical address when creating the parea.
