Date: Wed, 18 Jul 2012 18:50:16 -0700 From: H Hartley Sweeten <hartleys@...ionengravers.com> To: Linux Kernel <linux-kernel@...r.kernel.org> CC: <devel@...verdev.osuosl.org>, <abbotti@....co.uk>, <gregkh@...uxfoundation.org> Subject: [PATCH 57/90] staging: comedi: contec_pci_dio: cleanup "find pci device" code Add a couple local variables and reorder the tests to make to make the more concise. Change the printk to a dev_err when no match is found and reword the message.
