'amount_xferred' is used, but only in certain circumstances. Place the same stipulations on the defining/allocating of 'amount_xferred' as is placed when using it. We've been careful not to change any of the ordering semantics here. Fixes the following W=1 kernel build warning(s): drivers/scsi/aic7xxx/aic79xx_osm.c: In function ‘ahd_done’: drivers/scsi/aic7xxx/aic79xx_osm.c:1796:12: warning: variable ‘amount_xferred’ set but not used [-Wunused-but-set-variable] Link: https://lore.kernel.org/r/20200713080001.128044-24-lee.jones@linaro.org Cc: Hannes Reinecke <hare@suse.com> Reviewed-by: Hannes Reinecke <hare@suse.de> Signed-off-by: Lee Jones <lee.jones@linaro.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.
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.
