Subject: [PATCH 15/50] drm: remove agp_init() bus callback
Date: Wed, 11 Dec 2013 11:34:36 +0100	[thread overview]
Message-ID: <1386758111-3446-16-git-send-email-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <1386758111-3446-1-git-send-email-daniel.vetter@ffwll.ch>

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.
