This patchset removes functions that are not called in the driver but
are prototyped in card.h. Each commit limits its scope to one function
definition and related documentation in code.
Functions were checked for calls using the Elixir Cross Referencer and
git grep.
Per Stefano Brivio's recommendation, output of bloatometer script after
changes:
add/remove: 0/4 grow/shrink: 0/0 up/down: 0/-572 (-572)
Function old new delta
CARDbSoftwareReset 10 - -10
CARDvSetLoopbackMode 14 - -14
BBvExitDeepSleep 40 - -40
CARDbRadioPowerOn 508 - -508
Total: Before=36131, After=35559, chg -1.58%
Briana Oursler (4):
Staging: vt6655: Remove CARDbSoftwareReset definition.
Staging: vt6655: Remove CARDvSetLoopbackMode definition.
Staging: vt6655: Remove CARDbRadioPowerOn definition.
Staging: vt6655: Remove BBvExitDeepSleep definition.
Changes in v4:
- Update patch series title.
- Add patch 4/4 per suggestion of Julia Lawall.
- Patches 1/4-3/4 unchanged.
Changes in v3:
- Update language in patch series name at suggestions from
Stefano Brivio and Julia Lawall.
- Remove references to the changelog in the cover letter. It is
unrelated to this series.
Changes in v2:
- Add output of bloatometer.
- Change language from "uncalled function" to "function...that
is never called" in each patch description within the series.
