Subject: drm/vc4: Mark the device as active when enabling runtime PM.
X-Git-Tag: archive/raspbian/4.9.82-1+deb9u3+rpi1_jessie~5^2~229
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=16d7d09eb48ba2d87b2aea9874138ad01d8bc402;p=linux-4.9.git

drm/vc4: Mark the device as active when enabling runtime PM.

Failing to do so meant that we got a resume() callback on first use of
the device, so we would leak the bin BO that we allocated during
probe.
