I'm not subscribed to linux-kbuild and the browser won't do
save-as-text, so I typed it all in again.  Please check the below.

I'll put this in my mainline-later queue, which means I'll send it
Linuswards next week if it doesn't pop up in linux-next before then.

The changelog doesn't actually describe this patch as a regression fix.
It makes the patch look like a regular old bugfix.  And the changelog
doesn't describe the severity of the bug either.  Please do pay
attention to such details to guide others in deciding which kernel
version(s) need fixing.


From: Riku Voipio <riku.voipio@linaro.org>
Subject: builddeb: remove debian/files before build

As debian/files keeps accumulating entries, the changes file will end up
growing indefinelty.  Remove the file in clean rule and before build
starts.

Fixes: 3716001bcb7f ("deb-pkg: add source package")
