The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, but the implementation in this
driver returns an 'int'.
Fix this by returning 'netdev_tx_t' in this driver too and

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type defining 'NETDEV_TX_OK' but this
driver returns '0' instead of 'NETDEV_TX_OK'.
Fix this by returning ''NETDEV_TX_OK' instead of 0.

This one is questionnable because:
1) if !node->proc, then '&node->proc->inner_lock' is not acquired
since it doesn't even exist.
2) OTOH, the function can't have the annotation 100% right because
it semantics allows unbalanced locking depen

The method struct drm_connector_helper_funcs::mode_valid is defined
as returning an 'enum drm_mode_status' but the driver implementation
for this method uses an 'int' for it.
Fix this by using 'enum drm_mode_status' in the driver too.
