Subject: isdn: i4l: Remove ASYNC_CTS_FLOW
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=317c1360200059a7a8a832294a58409c73b784bf;p=openwrt%2Fstaging%2Fblogic.git

isdn: i4l: Remove ASYNC_CTS_FLOW

ISDN4Linux always enables CTS flow control and does not use the
tty_port_cts_enabled() helper function; remove ASYNC_CTS_FLOW
state enable/disable.
