Subject: [PATCH] Trivial patch to remove list member from struct tcx_par in drivers/video/tcx.c
Date: Mon, 10 Oct 2005 21:30:35 -0500	[thread overview]
Message-ID: <434B23CB.7000609@gmail.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 502 bytes --]

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,

Hareesh Nagarajan
