[PATCH 2/2] hwmon: (asus-ec-sensors) increase timeout for locking ACPI mutex

[Eugene Shalygin <eugene.shalygin@gmail.com>]

From: Ben Copeland <ben.copeland@linaro.org>

Some motherboards require more time to acquire the ACPI mutex,
causing "Failed to acquire mutex" messages to appear in the kernel log.
Increase the timeout from 500ms to 800ms to accommodate these cases.
