docbook: fix fatal error in linux/input.h

[Randy Dunlap]

Hi,

Recent commit 8613e4c2872a87cc309a42de2c7091744dc54d0e:
Author: Mauro Carvalho Chehab <mchehab@xxxxxxxxxx>
Date:   Thu Sep 9 21:54:22 2010 -0700
    Input: add support for large scancodes

causes a fatal error in docbook generation:

linux-2.6.36-git8/DOC1/Documentation/DocBook/device-drivers.xml:40690: parser error : StartTag: invalid element name
#define INPUT_KEYMAP_BY_INDEX	(1 << 0)
                             	    ^

I think that this message comes from xsltproc, but I'm not positive about that.
I also don't know of a really good fix for it.  However, I did find 2 ways to
work around the error:

a/ move the #define value to after the end of the struct input_keymap_entry, like:

/* flags bits: */
#define INPUT_KEYMAP_BY_INDEX	(1 << 0)

or
b/ don't use the "<< 0" (can leave the #define where it is in this case):
#define INPUT_KEYMAP_BY_INDEX	(1)

I have tested both of these patches and they work OK.
Are you OK with either of them?  or want to choose one?

thanks,
---
