Hi Krzysztof,

Today's linux-next build (x86_64 allmodconfig) failed like this:

drivers/net/wan/hdlc_ppp.c: In function 'ppp_cp_parse_cr':
drivers/net/wan/hdlc_ppp.c:384: error: 'struct hdlc_device' has no member named 'stats'
drivers/net/wan/hdlc_ppp.c:390: error: 'struct hdlc_device' has no member named 'stats'
drivers/net/wan/hdlc_ppp.c: In function 'ppp_rx':
drivers/net/wan/hdlc_ppp.c:552: error: 'struct hdlc_device' has no member named 'stats'

Caused by commit 198191c4a7ce4daba379608fb38b9bc5a4eedc61 ("WAN: convert
drivers to use built-in netdev_stats") from Linus' tree interacting with
commit 2c7275708f373ac387352f13e509fd0c7679e12c ("WAN: new synchronous
PPP implementation for generic HDLC").

I have to wonder if this was even build tested ...

I added the following patch.
