From 2c695fa0444273c7139a3ca4c324c95498a0bfed Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 11 Dec 2013 11:34:36 +0100 Subject: [PATCH] drm: remove agp_init() bus callback The PCI bus helper is the only user of it. Call it directly before device-registration to get rid of the callback. Note that all drm_agp_*() calls are locked with the drm-global-mutex so we need to explicitly lock it during initialization. It's not really clear why it's needed, but lets be safe. v2: Rebase on top of the agp_init interface change. v3: Remove the rebase-fail where I've accidentally killed the ->irq_by_busid callback a bit too early.
