If mainline breaks, you should at least make an attempt to either fix your
driver, or call for help.  If you drop back to a stable kernel and don't get the
problem fixed, you're going to be stuck on that stable release (which is the
single biggest reason you see so many boxes with wonky hardware that are
still stuck on 3.12 or other ancient kernels - they have out-of-tree drivers that
nobody ever bothered updating...)

And of course, try to get your driver into the mainline kernel upstream. At that
point, whenever somebody changes a kernel API, it's *their* job to fix anything
in-tree that breaks - including your driver.  If you are bothered by that and want
some control over it, list yourself as the maintainer so patches get passed to you
for putting into upstream.
