| |
From: Gyorgy Jeney
If the 8250_early driver uses bt_ioremap, find_port() is unable to find the correct device since the address returned by ioremap is different to that returned by bt_ioremap for the same address. Since no more than one device occupies the same physical address, compareing the physical addresses should be safe.
