Because if yes, most symbols (I did not check all) used by your drivers seems to be exported with EXPORT_SYMBOL, and not EXPORT_SYMBOL_GPL, so your driver, even with a proprietary license should be able to access them. I would recommend you mention your linux version, and the relevant kernel configuration parts. ^ permalink raw reply [flat|nested] 5+ messages in thread
