And you can always limit the bisect to a certain directory, but the risk
here is that if the regression is outside ath10k bisect won't find it.
So you need to carefully consider is it safe to do or not. From the man
page:

"Cutting down bisection by giving more parameters to bisect start

       You can further cut down the number of trials, if you know what
       part of the tree is involved in the problem you are tracking
       down, by specifying path parameters when issuing the bisect start
       command:

           $ git bisect start -- arch/i386 include/asm-i386"

Also if you can even just narrow down the regression to a smaller set of
patches, let's say few hundred, might make it easier to find the
regression.
