It will cause null-ptr-deref if platform_get_resource_byname() returns NULL,
we need check the return value.

If platform_get_resource_byname() returns an error, it's probably
because the name cannot be found. So I think this error message is
more accurate:
"could not find rxfifo or txfifo resource"
