From 726612b6b8259afa41d265a2722991c87f059223 Mon Sep 17 00:00:00 2001 From: Israel Rukshin Date: Tue, 24 Mar 2020 17:29:42 +0200 Subject: nvme: Make nvme_uninit_ctrl symmetric to nvme_init_ctrl Put the ctrl reference count at nvme_uninit_ctrl as opposed to nvme_init_ctrl which takes it. This decrease the reference count at the core layer instead of decreasing it on each transport separately. Also move the call of nvme_uninit_ctrl at PCI driver after calling to nvme_release_prp_pools and nvme_dev_unmap, in order to put the reference count after using the dev. This is safe because those functions use nvme_dev which is freed only later at nvme_pci_free_ctrl.
