Hello, the only change since v4 (sent starting with Message-Id: <20191217165816.19324-1-u.kleine-koenig@xxxxxxxxxxxxxx> is that I now added a file Documentation/ABI/testing/sysfs-class-led-trigger-tty in patch 3. As before this depends on patch "tty: drop useless variable initialisation in tty_kopen()" which is already on tty-next. Best regards Uwe Uwe Kleine-König (3): tty: rename tty_kopen() and add new function tty_kopen_shared() tty: new helper function tty_get_icount() leds: trigger: implement a tty trigger .../ABI/testing/sysfs-class-led-trigger-tty | 6 + drivers/leds/trigger/Kconfig | 7 + drivers/leds/trigger/Makefile | 1 + drivers/leds/trigger/ledtrig-tty.c | 153 ++++++++++++++++++ drivers/staging/speakup/spk_ttyio.c | 2 +- drivers/tty/tty_io.c | 87 +++++++--- include/linux/tty.h | 7 +- 7 files changed, 238 insertions(+), 25 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-class-led-trigger-tty create mode 100644 drivers/leds/trigger/ledtrig-tty.c -- 2.24.0
