From: Thomas Zimmermann Date: Thu, 27 Jun 2019 17:34:10 +0000 (+0200) Subject: drm/ast: Replace struct ast_framebuffer with GEM framebuffer helpers X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5ed7191dd97b212887a9cb4715c2ef09ea50ae47;p=openwrt%2Fstaging%2Fblogic.git drm/ast: Replace struct ast_framebuffer with GEM framebuffer helpers The ast driver's struct ast_framebuffer is a buffer object with GEM interface. There are already GEM framebuffer helpers that implement the same functionality. Convert ast to these.
