[PATCH] fix adbhid driver

From: Paul Mackerras (paulus@samba.org)
Date: Sun May 11 2003 - 23:21:56 EST


Linus,

This patch fixes some compilation errors in the adbhid driver (the
driver that connects ADB keyboards to the input layer), and adds a fix
for one powerbook model. Franz is the maintainer of this driver, and
I sent this patch to him some time ago for approval, but I didn't get
an answer. It has been in our linuxppc-2.5 tree for some time without
problems, so please apply it.

Regards,
Paul.
