Subject: [PATCH 048/203] PCI: mvebu: Check valid base address before port
|
|
setup
|
|
|
|
This driver does not fail to probe when it cannot obtain
|
|
a port base address. Therefore, add a check for NULL base address
|
|
before setting up the port, which prevents a kernel panic in such
|
|
cases.
