But, when you do this, you loose these lines from the .config file,
resulting in this diff in the file:

--- .config.save	2021-12-30 17:54:49.327896243 +0100

Is that really a good idea?  What's the default these days?

Also, to be pedantic, this is a [v2] patch, right?  :)

I'll wait for the other Android driver maintainers to review this before
applying it, if they agree it is ok to do.

thanks,
