[PATCH] Trivial patch to remove list member from struct tcx_par indrivers/video/tcx.c

From: Hareesh Nagarajan
Date: Mon Oct 10 2005 - 21:29:48 EST


This patch removes the list_head member 'list' from struct tcx_par in the file drivers/video/tcx.c among other trivial cleanups. The member 'list' is never used. It turns out that other frame buffer code like cg14.c, leo.c, bw2.c, etc. (in drivers/video) seem to have the same extra list_head member in their respective *_par structures.

The patch applies to the 2.6.13.4 kernel sources.

(AFAICT, I am not missing anything; If I am, I'm sorry for wasting your time.)

Thanks,
