* and advice of Greg Kroah-Hartman.
*
* Notes about the port:
* Release 0x00 of the GL518SM chipset doesn't support reading of in0,
* in1 nor in2. The original driver had an ugly workaround to get them
* anyway (changing limits and watching alarms trigger and wear off).
* We did not keep that part of the original driver in the Linux 2.6
* version, since it was making the driver significantly more complex
* with no real benefit.
*
* History:
* 2004-01-28 Original port. (Hong-Gunn Chew)
* 2004-01-31 Code review and approval. (Jean Delvare)
