Tony Battersby 5c50d84798 scsi: qla2xxx: target: Improve checks in qlt_xmit_response() / qlt_rdy_to_xfer()
Similar fixes to both functions:

qlt_xmit_response:

 - If the cmd cannot be processed, remember to call ->free_cmd() to
   prevent the target-mode midlevel from seeing a cmd lockup.

 - Do not try to send the response if the exchange has been terminated.

 - Check for chip reset once after lock instead of both before and after
   lock.

 - Give errors from qlt_pre_xmit_response() a lower priority to
   compensate for removing the first check for chip reset.

qlt_rdy_to_xfer:

 - Check for chip reset after lock instead of before lock to avoid
   races.

 - Do not try to receive data if the exchange has been terminated.

 - Give errors from qlt_pci_map_calc_cnt() a lower priority to
   compensate for moving the check for chip reset.

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 reStructuredText 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.
