[PATCH v3 08/10] staging: fsl-mc: dpbp: drop unused APIs
laurentiu.tudor at nxp.com
laurentiu.tudor at nxp.com
Tue Feb 7 07:43:51 PST 2017
From: Laurentiu Tudor <laurentiu.tudor at nxp.com>
Leave only APIs that will be used in upcomming drivers.
The patch is mostly mechanical, with a couple exceptions:
- getters/setters were not removed even if only one of
them is being used
- versioning API was also left in place
They will be added back on an as-needed basis.
