Subject: About closed-source module use GPL module function

Hi all,

Now I am porting a device driver to Linux, its source code is not opened.

In this module, I use some interface functions exported from GPL
module through EXPORT_SYMBOL macros. (not EXPORT_SYMBOL_GPL), For
example, register_sound_dsp() and so on.

Do I violate GPL? How to solve it?

Thanks a lot, any suggestion is appreciated.

This list is probably a not good source for (free) legal advice but
the simplest way to be sure is to release the source code under GPLv2.
HTH.

You should consult your company lawyer.
