This patch replaces rcu_assign_pointer(x, NULL) with RCU_INIT_POINTER(x, NULL) The rcu_assign_pointer() ensures that the initialization of a structure is carried out before storing a pointer to that structure. And in the case of the NULL pointer, there is no structure to initialize. So, rcu_assign_pointer(p, NULL) can be safely converted to RCU_INIT_POINTER(p, NULL) Signed-off-by: Monam Agarwal <monamagarwal123@xxxxxxxxx> --- drivers/staging/fwserial/fwserial.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/staging/fwserial/fwserial.c b/drivers/staging/fwserial/fwserial.c index 8af136e..4e42bde 100644 --- a/drivers/staging/fwserial/fwserial.c +++ b/drivers/staging/fwserial/fwserial.c @@ -1809,7 +1809,7 @@ static void fwserial_release_port(struct fwtty_port *port, bool reset) port->max_payload = link_speed_to_max_payload(SCODE_100); dma_fifo_change_tx_limit(&port->tx_fifo, port->max_payload); - rcu_assign_pointer(port->peer, NULL); + RCU_INIT_POINTER(port->peer, NULL); spin_unlock_bh(&port->lock); if (port->port.console && port->fwcon_ops->notify != NULL) @@ -2235,7 +2235,7 @@ static int fwserial_create(struct fw_unit *unit) port->max_payload = link_speed_to_max_payload(SCODE_100); dma_fifo_init(&port->tx_fifo); - rcu_assign_pointer(port->peer, NULL); + RCU_INIT_POINTER(port->peer, NULL); serial->ports[i] = port; /* get unique bus addr region for port's status & recv fifo */ -- 1.7.9.5 _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
