serial: bfin-uart: Fix auto CTS
Commit 64851636d568ae9f167cd5d1dcdbfe17e6eef73c, serial: bfin-uart: Remove ASYNC_CTS_FLOW flag for hardware automatic CTS, open-codes uart_handle_cts_change() when CONFIG_SERIAL_BFIN_HARD_CTSRTS to skip start and stop tx. But the CTS interrupt handler _still_ calls uart_handle_cts_change(); only call uart_handle_cts_change() if !CONFIG_SERIAL_BFIN_HARD_CTSRTS. cc: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Peter Hurley <peter@hurleysoftware.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
