>[ACPI] acpi_os_wait_semaphore(): don't complain about timeout
>
>The ASL Acquire operator (17.5.1 in ACPI 3.0 spec) is allowed to
>time out and return True without acquiring the semaphore.  There's
>no indication in the spec that this is an actual error, so this
>message should be debug-only, as the message for successful acquisition
>is.
