From: Laurentiu Tudor Date: Tue, 7 Feb 2017 15:43:51 +0000 (-0600) Subject: staging: fsl-mc: dpbp: drop unused APIs X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7337013473fdc5974329daf2ca788f1410bf46b2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git staging: fsl-mc: dpbp: drop unused APIs 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.
