drm/tegra: Fixes for v3.15-rc2
This contains a fix for the host1x driver writing to non-existent syncpt
registers.
A second commit removes an excess pad field in the parameter structure
for the DRM_TEGRA_SUBMIT IOCTL. Archeaology on earlier versions of this
file indicates that this was once there to pad an uneven number of u32
u32 fields, of which one was subsequently removed. Unfortunately nobody
remembered to get rid of the padding when that happened.
Both of these commits are Cc: stable because they fix issues that were
introduced back in v3.10.
