Merge patch series "Simplify multiple create*_workqueue() invocations"

Bart Van Assche <bvanassche@acm.org> says:

Hi Martin,

Multiple SCSI drivers use snprintf() to format a workqueue name before
invoking one of the create*_workqueue() macros. This patch series
simplifies such code by passing the format string and arguments to
alloc_workqueue(). Additionally, the structure members that are only
used as a temporary buffer for formatting workqueue names are
removed. Please consider this patch series for the next merge window.

Thanks,

Bart.
