[PATCH v9 00/11] Introduce the Counter subsystem

[William Breathitt Gray <vilhelm.gray@gmail.com>]

Changes in v9:
 - Prefix exported symbols with "counter_" to make counter namespace
   explicit and clear
 - Replace scnprintf and snprintf lines with sprintf in 104-quad-8.c
   since we're dealing with sysfs files

This revision is functionally identical to the last; changes in this
version were made to improve code clarity. Andrew Morton suggested
improving the names of the exported symbols to clean up the Counter
subsytem namespace. This revision adds a "counter_" prefix to the
exported symbols to keep the namespace tidy and these symbols as
clearly part of the Counter subsystem.

Andrew Morton also brought up a good point that the Generic Counter
"signal" terminology could conflict with the existing established use of
the term in other areas of the Linux kernel. I've changed the major
exported symbols in counter.h that used the "signal_" naming covention
to now use a "counter_signal_" naming convention in order to help
prevent this confusion; I've made similar changes to symbols in
counter.c as well. If this naming still causes trouble, we can consider
alternative names for this component.
