This patch fixes the network driver cpmac.c for compilation with
|
||
|
|
configuration option CONFIG_NETDEVICES_MULTIQUEUE.
|
||
|
|
|
||
|
|
These compiler warnings are fixed by the patch:
|
||
|
|
drivers/net/cpmac.c: In function 'cpmac_end_xmit':
|
||
|
|
drivers/net/cpmac.c:630: warning: passing argument 2 of 'netif_subqueue_stopped' makes pointer from integer without a cast
|
||
|
|
drivers/net/cpmac.c:641: warning: passing argument 2 of 'netif_subqueue_stopped' makes pointer from integer without a cast
|
||
|
|
drivers/net/cpmac.c: In function 'cpmac_probe':
|
||
|
|
drivers/net/cpmac.c:1128: warning: unused variable 'i'
|
||
|
|
|
||
|
|
During runtime, the unpatched driver raises a fatal runtime exception.
|
||
|
|
This is fixed by calling __netif_subqueue_stopped instead
|
||
|
|
of netif_subqueue_stopped, too.
|
||
|
|
|
||
|
|
Two additional code parts were modified for CONFIG_NETDEVICES_MULTIQUEUE
|
||
|
|
because other drivers do it in the same way.
