Currently the cached state stays valid and the new state may not -be read when a notification occurs. This can lead to a udev event -showing that the battery has changed but the sysfs state will still have -the cached state values. This change invalidates the update time forcing -the state to be updated before notifying the power_supply subsystem of -the change. - -Signed-off-by: Mathew King <mathewk@chromium.org> ---- - drivers/acpi/battery.c | 1 + - 1 file changed, 1 insertion(+) - -diff --git a/drivers/acpi/battery.c b/drivers/acpi/battery.c -index 366c389175d8..ab7fa4879fbe 100644 ---- a/drivers/acpi/battery.c -+++ b/drivers/acpi/battery.c -@@ -981,6 +981,7 @@ static int acpi_battery_update(struct acpi_battery *battery, bool resume) - acpi_battery_init_alarm(battery); - } - -+ battery->update_time = 0; - result = acpi_battery_get_state(battery); - if (result) - return result; |
