Subject[PATCH 4.19 117/243] gpu: host1x: Fix syncpoint ID field size on Tegra186
Date
From: Thierry Reding <treding@nvidia.com>

[ Upstream commit 2fc777ba8422e4a38cae61537ad6a26435a86fb8 ]

The number of syncpoints on Tegra186 is 576 and therefore no longer fits
into 8 bits. Increase the size of the syncpoint ID field to 10 in order
to accomodate all syncpoints.
