How to Relinquish ownership of an LP investment

I have a small investment in the General Partner of an old limited partnership investment (circa 2003). It is my only remaining investment that results in a K-1 and this requires me to go on extension every year since the K-1 is not available until October usually. The K-1 typically does not have any figures higher than $10 yet they claIm that the fund will remain open for at least 2 more years.  I am really done with it.  Is there a way that I can officially advise the investment manager that I relinquish ownership so that I do not have to fuss with the K-1 for these small amounts and continually go on extension?  Please let me know if it's possible and if so, how to do this. Thank you.
