Subject: [patch] vmwgfx: return -EFAULT instead of number of bytes remaining
Date: Tue, 18 Oct 2011 06:09:19 +0000	[thread overview]
Message-ID: <20111018060919.GC27732@elgon.mountain> (raw)

The intent here was to return an error code, but instead the code
returns the number of bytes remaining (that weren't copied).
