Subject: drm_modeset_lock oops in next
Date: Fri, 7 Apr 2017 08:56:50 -0700	[thread overview]
Message-ID: <20170407155649.GI13234@atomide.com> (raw)

Hi,

Looks like current next now oopses at least for omapdrm
when starting X. Reverting commit d20afeb3e2f9 ("Merge
remote-tracking branch 'drm-misc/for-linux-next'") makes
things work again.

Any ideas what might be causing the oops below?

Regards,

Tony
