From f78660123ff8e35e8098eefb8f8087a916239108 Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Fri, 25 Jul 2014 10:04:50 +0100 Subject: [PATCH] staging: comedi: amplc_pc236: no need to manipulate PCI ref count Now that this driver no longer supports "manual" attachment of PCI devices in its `attach` hook (`pc236_attach()`), it no longer has code that searches for a suitable PCI device and increments its reference count. Since the driver no longer has any reason for incrementing and decrementing the PCI device's reference count, the calls to `pci_dev_get()` and `pci_dev_put()` can be removed.
