Hi Greg,
After merging the staging tree, today's linux-next build (x86_64
allmodconfig) failed like this:
ERROR: "__bad_udelay" [drivers/staging/gma500/psb_gfx.ko] undefined!
Caused by commit 1e585b52fd8e ("gma500: Add the Oaktrail HDMI support")
interacting with commit a87e553fabe8 ("asm-generic: delay.h fix udelay
and ndelay for 8 bit args"). I have applied the follwowing patch for
today:
From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>
Date: Mon, 25 Jul 2011 15:18:44 +1000
Subject: [PATCH] gma500: udelay(20000) it too long again
so replace it with mdelay(20).
Fixes build error:
ERROR: "__bad_udelay" [drivers/staging/gma500/psb_gfx.ko] undefined!
