[ Upstream commit 362b5da3df ]
Clang warns when an enumerated type is implicitly converted to another.
drivers/scsi/isci/request.c:3476:13: warning: implicit conversion from
enumeration type 'enum sci_task_status' to different enumeration type
'enum sci_status' [-Wenum-conversion]
status = sci_controller_start_task(ihost,
~ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/scsi/isci/host.c:2744:10: warning: implicit conversion from
enumeration type 'enum sci_status' to different enumeration type 'enum
sci_task_status' [-Wenum-conversion]
return SCI_SUCCESS;
~~~~~~ ^~~~~~~~~~~
drivers/scsi/isci/host.c:2753:9: warning: implicit conversion from
enumeration type 'enum sci_status' to different enumeration type 'enum
sci_task_status' [-Wenum-conversion]
return status;
~~~~~~ ^~~~~~
Avoid all of these implicit conversion by just making
sci_controller_start_task use sci_status. This silences
Clang and has no functional change since sci_task_status
has all of its values mapped to something in sci_status.

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.
