From 692c0e78a52e62c31ed44d31eb66dafd439e5446 Mon Sep 17 00:00:00 2001 From: Radha Mohan Chintakuntla Date: Fri, 9 Apr 2021 01:06:27 -0700 Subject: [PATCH] raw/octeontx2_dma: assign PCI device in DPI VF The PCI device address is being used for sending mailbox which was introduced in previous commit which replaced the macros so that multiple DPI blocks in the hardware can be supported. This patch fixes a NULL pointer access by assigning the PCI device structure to dpivf.
