[PATCH 1/1] video: fbdev-SIS: Deletion of unnecessary checks before the function call "pci_dev_put"

From: Markus Elfring <elfring@users.sourceforge.net>

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.
