It's been a useless no-op for long enough in 2.6 so I figured it's time to remove it. The number of people that could object because they're maintaining unified 2.4 and 2.6 drivers is probably rather small.

* Description:
|

|
|
* This is the main module of the Linux GE driver.
|
|
*
|
|
* All source files except skge.c, skdrv1st.h, skdrv2nd.h and sktypes.h
|
|
* are part of SysKonnect's COMMON MODULES for the SK-98xx adapters.
|
|
* Those are used for drivers on multiple OS', so some thing may seem
|
|
* unnecessary complicated on Linux. Please do not try to 'clean up'
|
|
* them without VERY good reasons, because this will make it more
|
|
* difficult to keep the Linux driver in synchronisation with the
|
|
* other versions.
|

*
|
|
* Include file hierarchy:
