From: Boris Brezillon Date: Mon, 28 Nov 2016 14:56:53 +0000 (+0100) Subject: drm/atmel-hlcdc: Rework the fbdev creation logic X-Git-Tag: v4.14-rc1~1422^2~33^2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=db02b7614a54bf0bf548db07bc8d3e7518fd9481;p=platform%2Fkernel%2Flinux-rpi3.git drm/atmel-hlcdc: Rework the fbdev creation logic Now that we wait for DRM panels to be available before registering the DRM device (returning -EPROBE_DEFER if the panel has not been probed yet), we no longer need to put the fbdev creation code in ->output_poll_changed(). This removes the 10 secs delay between DRM dev registration and fbdev creation (polling period = 10 seconds).
