From: Thomas Hellstrom Date: Thu, 4 Oct 2018 22:38:17 +0000 (+0000) Subject: drm/vmwgfx: Fix up the implicit display unit handling X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9d9486e43728cd513e10ed3dd54e156c8ab7bd2a;p=openwrt%2Fstaging%2Fblogic.git drm/vmwgfx: Fix up the implicit display unit handling Make the connector is_implicit property immutable. As far as we know, no user-space application is writing to it. Also move the verification that all implicit display units scan out from the same framebuffer to atomic_check().
