Prev: [PATCH 38/67] cdc-acm: remove dead code
Next: [PATCH 39/67] tty: introduce wait_event_interruptible_tty
From: Greg Kroah-Hartman on 5 Aug 2010 18:50
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"
