> Hello,

> This patch series addresses an issue in the Xilixn ZynqMP DPDMA driver that
> causes a display freeze after 65536 frames. The first three patches include a
> small compilation breakage issue (1/4) and enhancements to the messages
> logged by the driver (2/4 and 3/4). The last patch fixes the freeze bug. Please
> see individual patches for details.
