Subject: s390/pci: Delete an unnecessary check before the function call "pci_dev_put"
X-Git-Tag: v5.15~13229^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=64a40c84001e55001a4d80496b6b56e4d04e4360;p=platform%2Fkernel%2Flinux-starfive.git

s390/pci: Delete an unnecessary check before the function call "pci_dev_put"

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.
