Date: Wed, 13 Jun 2012 15:42:12 -0700 From: H Hartley Sweeten <hartleys@...ionengravers.com> To: Linux Kernel <linux-kernel@...r.kernel.org> CC: <devel@...verdev.osuosl.org>, <abbotti@....co.uk>, <fmhess@...rs.sourceforge.net>, <gregkh@...uxfoundation.org> Subject: [PATCH 07/15] staging: comedi: 8255: refactor subdev_8255_init Refactor the initialization of the 8255 so that the private data allocation is done before the subdevice is setup. This makes sure that the setup is complete. Also, add a bit of whitespace to improve the readability.
