Always.

It's not a big issue for your patches. These are inevitably fixes and
I'll pick an appropriate tree depending on where we are in the cycle,
how likely one is to hit the issue, whether the driver is widely used,
etc.

Vendor driver submissions, however, are generally huge. Sometimes 50+
patches per submission window. And during this window I often get on the
order of 10 to 20 patches for the same driver in the fixes tree. It is
not always easy to determine whether a bug fix series is for one tree or
the other.
