Subject: [PATCH 287/381] 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.
