From 4354d64ea90c4caf6f14522f5bf357e4e4857886 Mon Sep 17 00:00:00 2001 From: Souptick Joarder Date: Tue, 31 Jul 2018 00:53:26 +0530 Subject: drm: Remove drm_fbdev_cma_set_suspend() drm_fbdev_cma_set_suspend() is not getting called from any other places. If there is no plan to use it in future we can remove this API.

The reason being that the planes contain subsampled (ie reduced) data (by a factor of 2) and thus while calculating the byte position coresponding to the x and y co-ordinates, one needs to divide it with the sampling factor.
