Subject: [PATCH 10/28] staging: comedi: amplc_pci230: absorb pci230_alloc_private()
Date: Mon, 1 Sep 2014 12:03:42 +0100 [thread overview]
Message-ID: <1409569440-10979-11-git-send-email-abbotti@mev.co.uk> (raw)
In-Reply-To: <1409569440-10979-1-git-send-email-abbotti@mev.co.uk>
`pci230_alloc_private()` is now only called from `pci230_auto_attach()`
to allocate private device storage and initialize various spin-lock
members therein. Absorb the body of `pci230_alloc_private()` into
`pci230_auto_attach()` itself.
