This patch works. The patch contains some small changes in the function
noname_map_irq compared to your previous patch and these changes make it
work. If I revert these changes, networking doesn't work.
I'm attaching dmesg of working kernel (4.14.12 with this patch) and
non-working kernel (4.14.12 with your previous patch with 'pr_info("%s:
level bits' added).
