Yihang Li 6491d9ea93 scsi: hisi_sas: Rollback some operations if FLR failed
[ Upstream commit 7ea3e7763c50b20a8bd25cf524ea0c6463de69be ]

We obtain the semaphore and set HISI_SAS_RESETTING_BIT in
hisi_sas_reset_prepare_v3_hw(), block the scsi host and set
HISI_SAS_REJECT_CMD_BIT in hisi_sas_controller_reset_prepare(), released
them in hisi_sas_controller_reset_done(). However, if the HW reset failure
in FLR results in early return, the semaphore and flag bits will not be
release.

Rollback some operations including clearing flags / releasing semaphore
when FLR is failed.

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.
