[PATCH v4 4/5] gpio: sysfs: emit chardev line-state events on active-low changes

[Bartosz Golaszewski <brgl@xxxxxxxx>]

From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>

The sysfs active_low attribute doesn't go through the usual paths so it
doesn't emit the line-state event. Add the missing call to
gpiod_line_state_notify() to gpio_sysfs_set_active_low().
