[PATCH] staging: comedi: adl_pci9118: Delete an unnecessary check before the function call "pci_dev_put"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sat, 27 Jun 2015 13:50:43 +0200

The pci_dev_put() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
