[linux-sunxi] [PATCH] drm/sun4i: wait on implicit fence before display

[Jernej Škrabec]

Hi,

Dne ponedeljek, 19. november 2018 ob 15:33:11 CET je Qiang Yu napisal(a):
> Render like lima will attach a fence to the framebuffer
> dma_buf, display like sun4i should wait it finish before
> show the framebuffer. Otherwise tearing will be observed.

Please resend this patch to all emails listed when running "scripts/
get_maintainer.pl" on this patch. You are missing at least sunxi maintainers.

Best regards,
Jernej
