Subject: IB/mthca: NULL arg to pci_dev_put is OK
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3491ab63b45ea9b485683574081ed8535d42f2da;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

IB/mthca: NULL arg to pci_dev_put is OK

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.
