[dpdk-dev] [PATCH] devtools: relax headline prefix check

[Tomasz Duszynski]

In order to avoid code duplication common code shared across drivers
is stored under drivers/common.

Currently if one needs to introduce changes to common and particular
driver i.e common/driver and net/driver separate patches needs to be
prepared otherwise warning about wrong headline prefix gets printed.

In order to avoid that script should allow cases where changes to
drivers/common/driver and drivers/group/driver belong to the same patch.

No please don't split patches just to make a script happy :)
We can tolerate few warnings if not meaningful.
But I agree it would be better to avoid such wrong warning.

It means you allow one common subdir and exactly one non-common subdir.
I think it is too much restrictive because it makes sense
to change a shared code and several related drivers.

Thanks for working on such improvement.
