Subject: [PATCH] mwlwifi: fix PCIe DT node null pointer dereference
|
|
|
|
pci_bus_to_OF_node() used to get the PCI bus DT node
|
|
returns node if found or NULL if none is found.
|
|
|
|
Since the return of pci_bus_to_OF_node() is not checked in
|
|
the DT node name print it will cause a null pointer
|
|
dereference and crash the kernel.
|
|
|
|
So first check whether the node is not NULL and then print.
