From db17c640e7a9e38db1b9c300a339d54f2cd2b95c Mon Sep 17 00:00:00 2001 From: Laurentiu Tudor Date: Tue, 7 Feb 2017 09:43:53 -0600 Subject: [PATCH] staging: fsl-mc: dprc: drop unused APIs Leave only APIs that area actually used in the bus driver. 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.
