This way the compiler warns when a new value is added to the enum but
not the string transation like:
drivers/net/ethernet/ibm/ibmvnic.c: In function 'adapter_state_to_string':
drivers/net/ethernet/ibm/ibmvnic.c:832:2: warning: enumeration value 'VNIC_FOOBAR' not handled in switch [-Wswitch]
switch (state) {
^~~~~~
drivers/net/ethernet/ibm/ibmvnic.c: In function 'reset_reason_to_string':
drivers/net/ethernet/ibm/ibmvnic.c:1935:2: warning: enumeration value 'VNIC_RESET_FOOBAR' not handled in switch [-Wswitch]
switch (reason) {
^~~~~~

This trick works.
Since the original code does not generate gcc warnings/errors, should
this patch be sent to net-next as an improvement?

Hi Michal,
Thank you for reposting the patch and including the Ack-by tag. I
think you need to wait till next Tuesday or so when net-next reopens,
then you can repost the patch.
http://vger.kernel.org/~davem/net-next.html.
Thanks,
Lijun
