nvme-pci: properly report state change failure in nvme_reset_work
If the state change to NVME_CTRL_CONNECTING fails, the dmesg is going to be like: [ 293.689160] nvme nvme0: failed to mark controller CONNECTING [ 293.689160] nvme nvme0: Removing after probe failure status: 0 Even it prints the first line to indicate the situation, the second line is not proper because the status is 0 which means normally success of the previous operation. This patch makes it indicate the proper error value when it fails. [ 25.932367] nvme nvme0: failed to mark controller CONNECTING [ 25.932369] nvme nvme0: Removing after probe failure status: -16 This situation is able to be easily reproduced by: root@target:~# rmmod nvme && modprobe nvme && rmmod nvme Signed-off-by: Minwoo Im <minwoo.im.dev@gmail.com> Reviewed-by: Chaitanya Kulkarni <chaitanya.kulkarni@wdc.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
