The drbd code causes warnings that we cannot easily disable when
building with clang:
In file included from drivers/block/drbd/drbd_debugfs.c:10:
In file included from drivers/block/drbd/drbd_int.h:48:
In file included from include/linux/drbd_genl_api.h:53:
In file included from include/linux/genl_magic_struct.h:237:
include/linux/drbd_genl.h:300:1: warning: no case matching constant
switch condition '0'
There is nothing wrong with the code, and adding 'default:' labels
in the right place is enough to let clang shut up about the warning.
Fixes: ec2c35ac1ea2 ("drbd: prepare the transition from connector to
genetlink")
