- Subject: [PATCH] drm/vc4: Fix a framebuffer reference leak on async flip
- interrupt.
- We'd need X to queue up an async pageflip while another is
- outstanding, and then take a SIGIO. I think X actually avoids sending
- out the next pageflip while one's already queued, but I'm not sure.
- Signed-off-by: Eric Anholt <eric@anholt.net>
- (cherry picked from commit 48627eb8dc55c60d35794105f6f79fb627347dbd)
