Indeed, this is caused by including caamalg_qi2.h -> dpseci-debugfs.h ->
dpseci-debugfs.c.
Compiling this patch without the inclusion:
CC drivers/crypto/caam/dpseci-debugfs.o
In file included from drivers/crypto/caam/dpseci-debugfs.h:9:0,
from drivers/crypto/caam/dpseci-debugfs.c:8:
drivers/crypto/caam/caamalg_qi2.h:84:21: error: field 'napi' has incomplete type
struct napi_struct napi;
^
drivers/crypto/caam/caamalg_qi2.h:85:20: error: field 'net_dev' has incomplete
type
struct net_device net_dev;
^
scripts/Makefile.build:278: recipe for target
'drivers/crypto/caam/dpseci-debugfs.o' failed
Other driver files include linux/netdevice.h indirectly, via compat.h ->
linux/rtnetlink.h.
Most *.c files in drivers/crypto/caam solve dependencies by including
compat.h, but this approach is messy.
Let's keep the explicit inclusion then.
