From add9195e69c94b32e96f78c2f9cea68f0e850b3f Mon Sep 17 00:00:00 2001 From: Dexuan Cui decui@microsoft.com Date: Wed, 14 Jun 2023 21:44:49 -0700 Subject: [PATCH] PCI: hv: Remove the useless hv_pcichild_state from struct hv_pci_dev
The hpdev->state is never really useful. The only use in hv_pci_eject_device() and hv_eject_device_work() is not really necessary.
