From 8c4ccc4ab6f64e859d4ff8d7c02c2ed2e956e07f Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 9 Jul 2015 23:44:26 +0200 Subject: [PATCH] drm/probe-helper: Grab mode_config.mutex in poll_init/enable So on first looks this seems superflous since drivers should ensure correct ordering to not make this a problem. Otoh ordering constraints between hdp, fbdev load and enabling polling are already tricky on some hardware and it helps to be more robust. But the real goal is to just shut up a locking WARN_ON I'd like to add, which means init code gets some additional locks just for uniformity. v2: Also grab the lock for the public poll_enable, not just poll_init which is used for resume, with the same justification.
