-Subject: [PATCH] serial: ar933x_uart: Fix build failure with disabled console
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Andrey has reported on OpenWrt's bug tracking system[1], that he
-currently can't use ar93xx_uart as pure serial UART without console
-(CONFIG_SERIAL_8250_CONSOLE and CONFIG_SERIAL_AR933X_CONSOLE undefined),
-because compilation ends with following error:
-
- ar933x_uart.c: In function 'ar933x_uart_console_write':
- ar933x_uart.c:550:14: error: 'struct uart_port' has no
-                               member named 'sysrq'
-
-So this patch moves all the code related to console handling behind
-series of CONFIG_SERIAL_AR933X_CONSOLE ifdefs.

-Subject: [PATCH] leds: trigger: netdev: fix refcnt leak on interface rename
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Renaming a netdev-trigger-tracked interface was resulting in an
-unbalanced dev_hold().
-
-Example:
-> iw phy phy0 interface add foo type __ap
-> echo netdev > trigger
-> echo foo > device_name
-> ip link set foo name bar
-> iw dev bar del
-[  237.355366] unregister_netdevice: waiting for bar to become free. Usage count = 1
-[  247.435362] unregister_netdevice: waiting for bar to become free. Usage count = 1
-[  257.545366] unregister_netdevice: waiting for bar to become free. Usage count = 1
-
-Above problem was caused by trigger checking a dev->name which obviously
-changes after renaming an interface. It meant missing all further events
-including the NETDEV_UNREGISTER which is required for calling dev_put().
-
-This change fixes that by:
-1) Comparing device struct *address* for notification-filtering purposes
-2) Dropping unneeded NETDEV_CHANGENAME code (no behavior change)
-
-Fixes: 06f502f57d0d ("leds: trigger: Introduce a NETDEV trigger")
