Subject: [PATCH 27/28] staging: comedi: amplc_pci230: change pci230_handle_ao_fifo() return type
Date: Mon, 1 Sep 2014 12:03:59 +0100 [thread overview]
Message-ID: <1409569440-10979-28-git-send-email-abbotti@mev.co.uk> (raw)
In-Reply-To: <1409569440-10979-1-git-send-email-abbotti@mev.co.uk>
Change the return type of `pci230_handle_ao_fifo()` from `int` to
`bool`. A return value of `true` indicates the AO command is still
running.
