sc16is7xx: use LSR_TEMT_BIT in .tx_empty() LSR_TEMT_BIT (LSR bit 6) provides us exactly the information we need to determine if transmission is finished - FIFO level and shift register empty. We can save ourselves reading FIFO level explicitly if we use this bit. Signed-off-by: Jakub Kicinski <kubakici@wp.pl> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
