Prev: [PATCH 40/68] tty: reorder ldisc locking
Next: [PATCH 02/68] serial: There's no config CONSOLE
From: Greg Kroah-Hartman on 10 Aug 2010 18:20
From: Yegor Yefremov <yegor_sub1(a)visionsystems.de>

Adding UART_CAP_EFR and UART_CAP_SLEEP flags will enable sleep mode
and automatic CTS flow control for 16C950 UARTs. It will also avoid
capabilities detection warning like this:

"ttyS0: detected caps 00000700 should be 00000100"
