Merge tag 'drm/tegra/for-5.1-rc6' of git://anongit.freedesktop.org/tegra/linux into drm-fixes
drm/tegra: Fixes for v5.1-rc6
This contains a follow-up fix for the stream ID programming and a fix
for a regression on older Tegra devices (Tegra20 and Tegra30) that are
running into a division by zero trying to enable audio over HDMI.
