From: Rob Clark Date: Tue, 13 Jun 2017 14:22:37 +0000 (-0400) Subject: drm/msm/mdp4+5: move aspace/id to base class X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f59f62d592a0553bbff6c5b2ba66036becb01c4a;p=openwrt%2Fstaging%2Fblogic.git drm/msm/mdp4+5: move aspace/id to base class Before we can shift to passing the address-space object to _get_iova(), we need to fix a few places (dsi+fbdev) that were hard-coding the adress space id. That gets somewhat easier if we just move these to the kms base class. Prep work for next patch.
