arcnet: Add NULL check in com20020pci_probe()

Browse source

[ Upstream commit fda8c491db ]

devm_kasprintf() returns NULL when memory allocation fails. Currently,
com20020pci_probe() does not check for this case, which results in a
NULL pointer dereference.

Add NULL check after devm_kasprintf() to prevent this issue and ensure
no resources are left allocated.
