commit17605afaaeupstream. Since scsi_device_quiesce() skips SCSI devices that have another state than RUNNING, OFFLINE or TRANSPORT_OFFLINE, scsi_device_resume() should not complain about SCSI devices that have been skipped. Hence this patch. This patch avoids that the following warning appears during resume: WARNING: CPU: 3 PID: 1039 at blk_clear_pm_only+0x2a/0x30 CPU: 3 PID: 1039 Comm: kworker/u8:49 Not tainted 5.0.0+ #1 Hardware name: LENOVO 4180F42/4180F42, BIOS 83ET75WW (1.45 ) 05/10/2013 Workqueue: events_unbound async_run_entry_fn RIP: 0010:blk_clear_pm_only+0x2a/0x30 Call Trace: ? scsi_device_resume+0x28/0x50 ? scsi_dev_type_resume+0x2b/0x80 ? async_run_entry_fn+0x2c/0xd0 ? process_one_work+0x1f0/0x3f0 ? worker_thread+0x28/0x3c0 ? process_one_work+0x3f0/0x3f0 ? kthread+0x10c/0x130 ? __kthread_create_on_node+0x150/0x150 ? ret_from_fork+0x1f/0x30 Cc: Christoph Hellwig <hch@lst.de> Cc: Hannes Reinecke <hare@suse.com> Cc: Ming Lei <ming.lei@redhat.com> Cc: Johannes Thumshirn <jthumshirn@suse.de> Cc: Oleksandr Natalenko <oleksandr@natalenko.name> Cc: Martin Steigerwald <martin@lichtvoll.de> Cc: <stable@vger.kernel.org> Reported-by: Jisheng Zhang <Jisheng.Zhang@synaptics.com> Tested-by: Jisheng Zhang <Jisheng.Zhang@synaptics.com> Fixes:3a0a529971("block, scsi: Make SCSI quiesce and resume work reliably") # v4.15 Signed-off-by: Bart Van Assche <bvanassche@acm.org> Signed-off-by: Martin K.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
