From 88262703416be01d6770fbf55737e73edb60ee16 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 18 Jul 2012 18:42:57 -0700 Subject: [PATCH] staging: comedi: cb_pcidas64: cleanup "find pci device" code Add a couple local variables to make the tests more concise. Reorder the tests to make the for() loop checking for a matching boardtype quicker. Drop the dev_dbg for a match. It's just add noise. Reword the dev_err when no match is found.
