When receiving a notification that a FCP device lost its local link we usually update the fibre channel host object which represents that FCP device to reflect that. This notification/information can also surface when the FCP device is running through adapter recovery (exchange config and exchange port data return incomplete). When moving the scsi host object allocation and registration - and thus also the fibre channel host object allocation - to after the first exchange config and exchange port data, and this happens during the very first adapter recovery, these updates can not be done until after the scsi host object is allocated. Reorder the fc_host updates in zfcp_fsf_fc_host_link_down() so that they only happen after a check of whether the scsi host object is already allocated or not. During the first adapter recovery this will cause the skip of these updates if a link-down condition is detected, but we can repeat them after we allocated the scsi host object, if necessary. For any further link-down handling the only changes in the work flow are the slightly reordered assignments in zfcp_fsf_fc_host_link_down().

README
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.
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.
