Subject: [PATCH] via* : switch to pci_get_device refcounted PCI API
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=edceeaf50be1764db4aa7c1b19e540067a051e77;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[PATCH] via* : switch to pci_get_device refcounted PCI API

If we can clean up these remainders we can finally delete pci_find_*
