In order to not to start returning errors when new I2C_M flags are
added, change behavior to just ignore all flags that we don't know
about. This includes the I2C_M_DMA_SAFE flag that already exists.

Applied to for-current, thanks! I added also this sentence from v2 to
the description to justify stable: "but causes -EINVAL to be returned
for valid transactions."


Also, this driver has no dedicated maintainer. Is there someone up for
this task? There is probably little to do and it will speed up patch
acceptance because I pick patches once the driver maintainer is happy.

I think it falls under the 'TEGRA ARCHITECTURE SUPPORT' wildcard (Thierry and Jon). Do we need a more specific maintainer entry?

If it's helpful to Thierry and Jon, I guess I could pick it up.
