Subject: [PATCH] 8250_pci: Fix kernel panic when pch_uart is disabled
Date: Fri, 7 Oct 2011 13:39:49 +0900 [thread overview]
Message-ID: <1317962389-21786-1-git-send-email-tomoya-linux@dsn.lapis-semi.com> (raw)
Currently, ".setup" function is not set.
As a result, when detecting our IOH's uart device without pch_uart, kernel panic
occurs at the following of pciserial_init_ports().
for (i = 0; i < nr_ports; i++) {
if (quirk->setup(priv, board, &serial_port, i))
break;
So, this patch adds the ".setup" function.
We can use pci_default_setup because our IOH's uart is compatible with 16550.
